OU Kosher is the kosher certification division of the Orthodox Union, a U.S.-based organization that has supervised kosher production since 1923. It certifies food and other products as kosher, meaning they meet Jewish dietary law, and it serves three audiences: companies seeking certification, consumers checking whether a product is kosher, and the broader food industry. If you are a manufacturer exploring certification, a consumer verifying a symbol, or a buyer researching kosher supply, OU Kosher is the body behind the familiar "OU" mark.

What OU Kosher actually does

The Orthodox Union describes itself as holding "the most trusted kosher certification in the United States," and its certification work is the core of what the site presents. Two functions matter most:

• Certifying companies. Food producers apply to have their products and facilities supervised so they can carry an OU kosher symbol. The site states it has certified over 1.3 million products globally since 1923.
• Informing consumers. OU Kosher maintains searchable lists and resources so shoppers can confirm whether a specific product or category is kosher.

The organization also publishes educational material on kosher law and practice, including a glossary of kosher terms, an explanation of kosher symbols, and guidance on topics like checking fruits and vegetables.

Who the site is built for

The homepage organizes its content around three groups, and knowing which one you are tells you where to go:

For companies: getting certified

If you produce food and want OU certification, the site frames this as a defined process rather than a one-step application. The relevant pages are Get Certified, Steps to Certification, and How does OU Supervision Work?, which together explain what supervision involves. The site lists a dedicated applications and new certification contact line at +1 (212) 613-8372, and a "Company Login" for existing certified companies to manage their accounts.

A practical note: the site does not publish pricing for certification on the pages shown, so cost is something you would need to raise directly with the certification office rather than assume from the website.

For consumers: checking a product

Consumers have several tools on the site:

• Product Search — look up whether a specific item is OU-certified.
• Kosher Alerts — notices about certification changes or issues, useful if you rely on a product being kosher.
• Specialized lists — including a Beer List, Cheese List, Pas Yisroel List, Yoshon Search, and a Kosher for Passover Product Search, each covering a category with its own rules.
• Consumer Hotline — listed as +1 (212) 613-8241 x3 for questions.

The site also notes that most Americans eat some kosher-certified food daily without realizing it, and that certification appears on over 60% of America's produced foods that are certified kosher — from Oreo to Coca-Cola. That context explains why the consumer tools exist: the symbol is widespread, and verifying it is a routine need.

The scale behind the symbol

Two figures from the site are worth keeping in mind when judging how much weight the OU mark carries:

• Over 1.3 million products certified globally since 1923.
• Over $150 billion of kosher-certified products consumed annually, with spending described as continuing to rise.

These numbers reflect the organization's reach rather than any quality claim about individual products — the OU mark indicates kosher status, not nutrition or taste.

What the site does not tell you

A few things are absent from the material shown, so treat them as open questions rather than assumptions:

• Certification fees are not listed.
• Timelines for completing certification are not stated on the pages referenced.
• Eligibility details for specific product types would come from the application process itself.

For any of these, the certification office phone number and the "Get Certified" application are the direct routes.

Bottom line

OU Kosher is the Orthodox Union's kosher certification arm, operating since 1923 and covering over 1.3 million products. Companies come to it to obtain or manage certification; consumers come to it to verify products and read alerts. If you need to confirm a product is kosher, start with Product Search or the Consumer Hotline. If you want your product certified, start with "Get Certified" and call the certification office, since pricing and timelines are not published on the site.

A product that is OU kosher certified has been reviewed and supervised by the Orthodox Union (OU), one of the most widely recognized kosher certification agencies in the United States. In practice, that means the product and its production process meet Jewish dietary (kosher) requirements as verified by the OU, and the package carries the OU symbol as evidence. This matters most if you keep kosher, are shopping for someone who does, or simply want to know what the symbol on a label actually guarantees.

What "kosher" means in basic terms

Kosher refers to food that conforms to Jewish dietary law. The core rules cover:

• Permitted animals: Only certain animals are allowed, and they must be slaughtered and prepared in specific ways.
• Separation of meat and dairy: Meat and dairy products cannot be mixed or processed on the same equipment without proper kosher handling.
• Forbidden foods: Certain items, such as pork and shellfish, are not kosher.
• Production oversight: Even otherwise permitted ingredients must be produced under kosher-compliant conditions.

Because these rules extend into ingredients, equipment, and facilities, certification is how a company demonstrates that a product actually complies.

What the OU symbol tells you

The OU symbol on a package is the visible result of OU certification. It signals that the Orthodox Union has evaluated the product and its production and determined it meets kosher standards under OU supervision.

The OU describes itself as certifying over 1.3 million products globally since 1923, and its certification appears on a large share of produced foods in America. According to the OU, over 60% of America's produced foods that are certified kosher carry certification, and over $150 billion of kosher certified products are consumed annually. In other words, the symbol is common even on products bought by people who do not keep kosher.

How OU supervision works

OU supervision is not a one-time label approval. It is an ongoing relationship between the certifying agency and the company:

1. Application and review — A company applies for certification, and the OU reviews ingredients, suppliers, and production methods.
2. Supervision setup — Kosher requirements are built into the production process, including how equipment is used and cleaned.
3. Ongoing monitoring — The OU maintains supervision to confirm continued compliance.
4. Symbol use — Once certified, the company may display the OU symbol on approved products.

The OU provides public resources on this process, including "Steps to Certification," "How does OU Supervision Work?," a "Glossary of Kosher Terms," and a "Kosher Symbols" guide. These are useful if you want to understand what a specific symbol or product status means.

How to check a specific product

If you want to confirm whether a particular item is OU certified:

• Look for the OU symbol on the packaging.
• Use the OU product search on oukosher.org to look up products.
• Check the OU Kosher Alerts page, which flags changes or issues with certified products.
• Contact the OU Consumer Hotline at +1 (212) 613-8241 x3 for consumer questions.

For companies rather than consumers, the OU lists an Applications and New Certification Office at +1 (212) 613-8372 and a "Get Certified" application path.

Who this is for

• Kosher consumers: The OU symbol is a quick way to identify products certified to OU standards.
• Manufacturers and brands: OU certification can open access to kosher-observant markets and to the broader group of shoppers who look for kosher symbols.
• General shoppers: The symbol indicates third-party kosher supervision, even if you are not personally keeping kosher.

If your question is specifically about whether a product is kosher, the OU symbol plus the OU's own product search and alerts are the most direct ways to verify it.

A company applies for OU Kosher certification by submitting an application through the OU Kosher website or by calling the Applications and New Certification Office at +1 (212) 613-8372. The OU (Orthodox Union) has certified products since 1923 and currently certifies over 1.3 million products globally, making it one of the most widely recognized kosher certification marks in the United States. The application path below fits companies that produce food, beverages, or ingredients and want the OU symbol on their packaging.

Start With the Right Entry Point

The OU Kosher site provides a "Get Certified" section with a direct application link, plus a phone line for new certification inquiries. Companies already certified can use a separate "Company Login" for ongoing account access.

If your company operates outside the U.S., the site offers content in multiple languages, including Português, 中文, Bahasa Indonesia, 日本語, 한국어, Bahasa Melayu, Español, Italiano, Français, Filipino, ไทย, Tiếng Việt, Türkçe, and हिन्दी. There is also a dedicated China Kosher section, which is relevant if your manufacturing or export operations are based in China.

What the Certification Process Involves

The OU Kosher site outlines a "Steps to Certification" sequence and a separate explanation of "How does OU Supervision Work?" The general flow looks like this:

1. Apply. Submit the application form or call the new certification office. You describe your products, ingredients, and production facilities.
2. Review and scope. OU Kosher evaluates which products and production lines need supervision, and what ingredients or processes could affect kosher status.
3. Supervision setup. Once approved, OU establishes how supervision will work at your facility — this is where the "How does OU Supervision Work?" material becomes relevant to your operations.
4. Certification and letters. Certified companies receive Letters of Certification, which document which products carry the OU symbol.
5. Ongoing compliance. Certification is not one-time; supervision continues, and the OU maintains a Kosher Policy and Confidentiality Statement governing the relationship.

The exact requirements depend on your products and facilities, so treat the steps above as the framework rather than a fixed checklist. The OU's own "Steps to Certification" page is the authoritative sequence for your specific case.

Why Companies Choose OU Over Other Certifiers

The OU describes itself as having "the most trusted kosher certification in the United States." Several concrete factors support that positioning:

• Scale and history. Certifying since 1923, with over 1.3 million products certified globally.
• Market reach. Over 60% of America's produced foods that are certified kosher carry certification, and over $150 billion of kosher-certified products are consumed annually.
• Consumer recognition. The OU symbol is one of the most recognized kosher marks, which matters if your retail customers look for it by name.
• International support. Multilingual resources and a China Kosher program help companies outside the U.S. navigate certification.

The trade-off: OU certification involves ongoing supervision and compliance obligations, so it suits companies with the production volume and market ambition to justify that commitment. A smaller producer selling only locally may weigh whether the recognition benefit matches the effort.

What Certification Means for Market Access

Kosher certification is not only for kosher-observant consumers. The OU notes that most Americans eat some kosher food every day without realizing it — certification appears on a large share of supermarket products, from Oreo to Coca-Cola. For a company, the OU symbol can function as:

• A signal of third-party quality and ingredient oversight that some non-kosher consumers also seek.
• A requirement for selling into certain retail channels, distributors, or export markets.
• A differentiator on packaging in competitive food categories.

If your goal is entering markets or retail chains where the OU symbol is expected, certification is closer to a prerequisite than an optional add-on.

Practical Next Steps

1. Go to oukosher.org and use the "Get Certified" application link, or call +1 (212) 613-8372.
2. Prepare a list of your products, ingredients, and production facilities before you apply.
3. Review "Steps to Certification" and "How does OU Supervision Work?" so you understand the ongoing obligations, not just the initial approval.
4. If you are outside the U.S., check the language options and the China Kosher section for region-specific guidance.
5. Once certified, use Company Login for account management and expect Letters of Certification to document your certified products.

The OU's Kosher Policy and Confidentiality Statement are worth reading before you apply, since they define how the certification relationship works. For product-specific or consumer questions, the Consumer Hotline at +1 (212) 613-8241 x3 is the listed contact.

OU Kosher is widely trusted because the Orthodox Union has certified kosher products since 1923 and now oversees more than 1.3 million products globally. That combination of longevity, scale, and a recognizable symbol gives companies, consumers, and international buyers a common reference point. If you are evaluating a certification agency for a product line, or trying to understand why a specific symbol appears on packaging, the OU's history and reach are the main reasons it carries weight.

What the Orthodox Union actually does

The Orthodox Union (OU) is the organization behind OU Kosher. Its certification work covers three broad audiences:

• Companies — manufacturers apply for certification, receive supervision, and appear in OU's company directory and letters of certification.
• Consumers — a consumer hotline, product search, kosher alerts, and resource lists (beer, cheese, fruits and vegetables, Passover products) help verify what is certified.
• Food industry and trade — trade shows, featured companies, and China Kosher resources support manufacturers and exporters.

The OU describes itself as having the most trusted kosher certification in the United States, serving companies, consumers, and food industries worldwide.

Scale: the numbers behind the trust

These figures matter for a practical reason: a certification is only useful if buyers and consumers recognize it. A symbol that appears on a large share of supermarket products, from Oreo to Coca-Cola as OU notes, is one that retailers, importers, and shoppers already know how to read.

Why the certification is trusted

Long institutional history

Operating since 1923 means the OU has accumulated decades of supervision experience and case precedent across changing food technologies and ingredients. For a company choosing a certifier, that track record reduces uncertainty about how unusual ingredients or processes will be handled.

Global, multilingual reach

The OU Kosher site is available in many languages, including English, Português, 中文, Bahasa Indonesia, 日本語, 한국어, Bahasa Melayu, Español, Italiano, Français, Filipino, ไทย, Tiếng Việt, Türkçe, and हिन्दी. For exporters and international manufacturers, this means application and support channels exist in the languages their teams actually use, which matters when documentation has to be precise.

A dedicated China Kosher program

OU Kosher maintains a specific China Kosher section, reflecting how much kosher-certified production and sourcing runs through Chinese manufacturing. Companies sourcing ingredients or finished goods there can look for OU supervision rather than assuming a generic kosher claim is equivalent.

Consumer-facing verification tools

Trust is easier to maintain when claims can be checked. OU provides a product search, kosher alerts, letters of certification, and lists for specific categories such as beer, cheese, Passover products, and Yoshon. A consumer or buyer who doubts a label can look it up rather than rely on the packaging alone.

How this affects your decision

If you are a consumer: the OU symbol plus a product search or kosher alert check is a reasonable way to confirm a specific item. Note that certification applies to a specific product and production arrangement, not to a brand in general, so always verify the item in front of you.

If you are a manufacturer considering certification: the OU's scale and recognition can help with retail acceptance and export markets, but certification is a supervised relationship, not a one-time label. Expect application steps, supervision, and ongoing documentation. The OU lists a certification office at +1 (212) 613-8372 and an online application path.

If you are a buyer or importer: the multilingual support and China Kosher resources are relevant when your supply chain crosses languages and borders. Confirm the specific product and facility are covered by requesting the letter of certification rather than relying on the symbol alone.

Common points of confusion

• "OU" and "kosher" are not the same thing. Kosher is the standard; OU Kosher is one certification agency applying it. Other agencies exist, and their symbols differ.
• A certified brand does not mean every product is certified. Certification is product- and facility-specific.
• Recognition is not the same as suitability for your needs. A widely trusted certification still has to match your target market, your ingredient profile, and your production process.

For current details on applying, verifying a product, or checking a specific symbol, use the OU Kosher site's product search, letters of certification, and contact channels rather than secondhand summaries.

The fastest way to check whether a product carries OU Kosher certification is to use the Product Search tool on oukosher.org, or to look for the OU symbol on the packaging itself. If a product isn't in the search results, or the symbol on the label is unfamiliar, you can confirm by calling the OU Kosher Consumer Hotline at +1 (212) 613-8241 x3. The steps below cover each method, plus the specialty lists (beer, cheese, produce) and alert resources that answer most consumer questions without a phone call.

Method 1: Search the OU Product Database

The site's Product Search is the primary lookup tool for consumers.

1. Go to oukosher.org and find Product Search (listed under the Consumers section).
2. Enter the product or brand name.
3. Review the result: a match means the company and product are listed under OU supervision.

Expected result: you either find the product listed as OU certified, or you don't. If you don't find it, that does not automatically mean the product is non-kosher — it may be certified by a different agency, or the database entry may be under a slightly different product name. In that case, use the hotline.

Common snag: brand names and product names don't always match what's printed on the front of the package. Try the manufacturer's name as well as the product name.

Method 2: Read the Symbol on the Package

The OU symbol is the mark that identifies a product as certified by the Orthodox Union. The site maintains a Kosher Symbols reference page explaining the symbols and what they mean, which is useful when a label shows a symbol you don't recognize or a variation you haven't seen before.

If the symbol on the package doesn't match what the site describes, treat the certification as unconfirmed until you check with the OU directly.

Method 3: Call the Consumer Hotline

For anything the database and symbol guide don't resolve, the OU Kosher Consumer Hotline is +1 (212) 613-8241 x3. This is the appropriate route when:

• A product isn't in the search results but you want a definitive answer.
• A label symbol is ambiguous or damaged.
• You need to confirm a specific product variation (flavor, size, seasonal edition).

Companies with certification questions use a separate line: +1 (212) 613-8372 (Applications and New Certification Office). Consumers should use the hotline number instead.

Specialty Kosher Lists

Some categories are hard to judge from a package symbol alone, so the OU publishes dedicated lists under its Consumer Resources:

These lists exist because a general product search won't answer category-specific questions — for example, whether a particular cheese or beer is acceptable.

Alerts, FAQs, and Ongoing Updates

Kosher status can change. The OU publishes Kosher Alerts for products whose certification status has changed or been withdrawn, and a FAQS section plus Daf HaKashrus for detailed guidance. If you rely on a specific product regularly, checking alerts is worth doing rather than assuming a past result still holds.

For general background — what kosher means, how supervision works, and a glossary of terms — the site's Learn about Kosher section covers the basics, including "What is Kosher?" and "How does OU Supervision Work?"

Quick Decision Guide

• Product in hand, symbol looks standard → confirm against the Kosher Symbols page; if it matches, you're done.
• Want to verify a specific product → use Product Search.
• Product not found, or symbol unclear → call +1 (212) 613-8241 x3.
• Beer, cheese, produce, Passover, or Yoshon → use the matching specialty list rather than general search.
• Checking a product you've relied on before → check Kosher Alerts for status changes.
