Instructions and Details on Using Our Site

A. Do a Search: Type your search term or item in the “Search” box in the header.

By Product Name: The best results are achieved by first typing the Brand, then the specific Product, (and for large companies add the Country).

By UPC Bar Code: Alternatively, if you have the product in hand, you can also type in the entire UPC bar code number. For most, it is 12 digits in the USA and Canada, except for Trader Joe’s items. In other countries, it is usually 13 digits.

Once typed in, hit “Enter” on your computer keyboard, or tap on “Search” on your phone or mobile device.

B. Find Your Product: When an entry’s product image shows up, click on the blue product title to view it. Clicking on the picture will not take you to the product. Sometimes it may be a similar item within a list, and it will be highlighted in red. (If a product is not found, we usually have no information on it, or it may have been misspelled.)

C. View the Main Information on the Product.  The features of the product shown include:

1. Brand with Product Name or a general description for multiple products.

2. (Location Made) shows a location of origin if it’s important to know. If a brand’s products are made in multiple countries or exported, it’s necessary info. No location listing means it’s from the USA.

3. Status or Date Code (in orange) shows info needed to know for a product to be yoshon. A Status is usually “Yoshon”, or may be Yoshon under certain conditions, or could even be “Chodosh”. The Date Code shown to the left is the best buy cutoff date on the package as to when it becomes chodosh. In order for the product to be yoshon, the best by date on your package must always be before this date. (The same goes for Packing Dates or lot codes.)
If there are alternative Date Codes, they will be shown here with “or”.
If an item is yoshon with a specific lot number or date, it will have “Only” listed with it.

4. Multiple Products List: If there are two or more products in an entry with the same ingredients, and Date Code or Status.

5. Notes: Any important items concerning the specific product. It could be regarding a certain package size, hashgacha, an infestation, or a product recall.

6. Updated As Of: The green date is the time of the last reported update on the product’s info. This sample picture shows that the last update was from November 23, 2018.

Viewing Additional Information

Scroll down slightly to view “Additional Info”. (Pick whether you have a computer or mobile device, as they differ slightly.)

Computers (Left): Scroll down slightly, and below the picture will be the “Hechsher” tab (showing the Kosher Supervising Agency’s symbol) and “Additional Info” to its right.

Mobile Devices (Right): Scroll down until after the brand name logo of the product. Below it will show the “Hechsher” tab to the left, and “Additional Information” tab to the right.

Viewing the Hechsher


This shows a sample picture of the hechsher on the product. Sometimes, this can be a direct hint as to knowing whether your item is yoshon or not. Most hechsherim from the USA have to have yoshon on the label, but there are a few “Always-Yoshon” hechsherim from the UK and of course Israel. (See our sheet of “Always-Yoshon Hechsherim” on our “Updates and Downloads” page.

Viewing Additional Information

Additional Information

Shelf Life: If known, this is shown.

Grain Ingredient: This lists all grain ingredients in a product. If it contains no grain it has “No Problematic Ingredients”.

Designation: Any special designations (Parve, Dairy, Cholov Yisroel or Stam, Glatt Kosher Meat, Kosher for Passover, Pas Yisroel, etc.).

Kosher Supervision: Overseeing kosher agency. (A picture of the Hechsher is shown in “Hechsher” tab to the left.)

Yoshon Hashgacha: Rabbi or agency overseeing yoshon status. (Shown only if applicable).

Update Source: This is where TYNI has gotten its yoshon information for the product. (See Note below.)

UPC Barcode: If known, the complete UPC numbers of the product and its variations will appear here. If it is unknown, this will not be shown.

A Note On Our Sources: Usually for the USA most info is from the Guide to Chodosh. We also get yoshon info from COR or MK of Canada , UOS of South Africa, KLBD, KF, MBD, and Kedassia of the UK, and seberal reliable kashrut agencies in the USA. Occasionally we get info from reputable companies with reliable mashgichim. Some research is also done by TYNI itself. If it has originally Guide to Chodosh, it means that the original information came from Guide to Chodosh, but it may not have been listed in the current Guide.

Why a Different Product Can Be Displayed in a Specific Search

A Word About “Like-Kind” Products: Often, when a brand has similar products with the exact same grain ingredients and the same Date Code, they will be listed together under one product (as shown in note 5 above). A good example is pasta (shown below). If you searched for a certain brand of pasta in Whole Wheat Spaghetti, it may come up as the same brand, but showing a picture of Whole Wheat Spirals.

This is due to brands having multiple pasta shapes, but all still share the same ingredients and Date Code. When there are a great variety of shapes, all these “like-kind” products will be listed within one entry, so that if one of them is searched for it will come up in the results with the word highlighted in the initial search.

The same thing holds true for other products such as cereals. If two different cereals have the same exact problematic grain ingredients and the same Date Code, they may be listed together. This is also true for Yoshon items, or items with “No Problematic Ingredients” as well. Any products with different ingredients or different Date Codes are always put in completely separate entries.

Specific Questions If there are any questions about our site, please contact us at The Yoshon Network Inc. (TYNI) will answer basic questions only, or use our chatbot YAIR at the bottom right. Text, WhatsApp chat and Email are always the best way to contact us. We no longer answer questions by phone, as it is too labor intensive and we have limited volunteers.

Halachic/Yoshon Questions: If you have questions about yoshon products, you may want to contact Project Chodosh at
TYNI does not answer Halachic questions or give any kind of P’sak. Everyone must ask their own Rav. 

Specific Product Questions: If you have questions about a certain product, or know of a product made by a certain company, go to the Menu and click on “Brands“. (For mobile devices, click on the box with the lines in the upper right corner to view the menu.)
The “Brands” page shows a carousel of brand logos in alphabetical order. Click on the logo you need, and it will take you to that brand’s website (if there is one). If you are looking at a certain product entry, you can also click on the brand’s logo to go to their site. Usually a site will have their current contact information on a “Contact Us” page.

Future Endeavors

It is no secret, but TYNI is currently in the process of developing the Official App that will enable people to scan the UPC barcode of a product in the store to get its current yoshon information, as long as it’s is a product in our vast and ever changing database.
This development process takes much time and research. It is all a part of The Yoshon Network Inc.’s commitment to making the mitzvah of keeping yoshon as easy as possible.
