Google Merchant Center’s New 2026 Requirements: What Your Shopping Feed Needs Before Diwali

Google has quietly added two new requirements to its Merchant Center product data specification. One affects any business running local inventory ads. The other affects products that need warranty disclosure under a Canadian law. Neither change comes with a loud announcement or a clear deadline — which is exactly why advertisers should check their feeds now, before Diwali on November 8 and Black Friday on November 27 bring the year’s highest-stakes traffic.

This article explains both changes in plain terms, what we could verify directly from Google’s own documentation, and what remains open or unconfirmed.

Change 1: store_address Is Now a Required Attribute

Google’s Merchant Center Help page for store_address lists it plainly as “Required” for each applicable product. The attribute specifies the postal address of the physical store where a product is available — separate from store_code, which must still match the store codes in your verified Google Business Profile.

What this affects:

Local inventory ads (the paid Shopping format showing in-store stock) and free local product listings. Since local inventory ads became enabled by default for many linked Merchant Center accounts in August 2026, more advertisers than ever are now subject to this requirement, often without realising it.

What the field requires:

  • A complete, typo-free postal address, submitted once per product (it is not a repeatable field).
  • Unicode is technically accepted, but Google recommends ASCII characters with UTF-8 encoding to avoid errors.
  • Products sold across multiple stores need separate per-store inventory records — one address cannot cover several locations.

What happens if you skip it:

Google’s own help documentation states that products failing minimum requirements are disapproved, and Merchant Center flags the affected items in your account. For a brand depending on local-stock visibility during festive shopping, that is lost visibility at the worst possible time.

A genuinely useful distinction here: store_address does not replace store_code. You likely still need both — the address identifies the store, and the code links that store back to your Business Profile.

Change 2: A New Warranty Attribute, Driven by a Canadian Law

Google’s product data specification now documents a warranty attribute as required for products that need warranty information shown under regional law — explicitly citing Quebec’s Bill 29, Canada, which took effect October 5, 2026. For vehicle ads (a separate, Japan-only use case), the attribute remains optional.

How it works for general products:

  • Two sub-attributes, duration and duration_unit, are both required.
  • duration_unit defaults to months — but Quebec specifically requires the unit to be years.
  • The feed format is warranty(duration:duration_unit), with an example value like 6:year.

Why Quebec specifically:

Quebec’s Bill 29 amended the province’s Consumer Protection Act to require a prominent, displayed warranty period on 14 categories of goods — from 3 years on laptops and phones to 6 years on major appliances — shown near the advertised price, in-store, online, and in ads. Businesses cannot exclude or shorten that legal minimum.

What’s still unconfirmed:

Google has not published when the warranty duration will actually start appearing on live ads and listings, beyond saying it will begin “later this year.” Whether it will ever extend beyond Quebec to other markets is not stated either.

Why This Matters for India-Based Advertisers Right Now

store_address is the one with real, immediate local relevance: any Kolkata, Bengaluru, Delhi NCR, or Chandigarh retailer running local inventory ads — showing “in stock nearby” on Shopping listings — needs this field correct today, not after a disapproval notice arrives mid-festive-season.

warranty is narrower. It matters directly only if you sell into Canada, particularly Quebec. But it is worth watching as a pattern: Google is increasingly building region-specific legal-compliance fields directly into its global feed specification. A similar mandatory attribute tied to Indian consumer-protection requirements is plausible in the future, though nothing like that has been announced, and this should be read as an informed observation, not a prediction.

A Practical Pre-Festive Feed Audit

  1. Check whether local inventory ads are even enabled on your account. If you’re an online-only business, Google’s own guidance says to remove the local inventory add-ons entirely rather than chase an address requirement that doesn’t apply to you.
  2. If you do have physical stores, verify store_address matches your Google Business Profile exactly — same formatting, same spelling, for every location.
  3. Confirm store_code is still correctly linked — this requirement didn’t disappear; it now sits alongside the address field.
  4. If you sell into Canada, check your warranty data today, even though on-ad display hasn’t started — feed-side work takes longer than the display rollout will.
  5. Reprocess your data source after any fix, and request a review for previously disapproved items.
  6. Don’t wait for an error message. Several of these changes carry no stated deadline, which historically means Google can start enforcing with little notice.

Key Takeaways

  • store_address is now officially listed as required for local inventory ads and free local listings — this affects India-based retailers with physical stores, not just global brands.
  • warranty is required for products needing disclosure under Quebec’s Bill 29; it is optional elsewhere, including India, for now.
  • Google has not published a firm display start date for the warranty attribute or confirmed whether it will expand beyond Quebec.
  • A quick feed audit now avoids disapprovals during Diwali and Black Friday, when visibility matters most.

FAQs

  1. What is Google Merchant Center’s store_address attribute?
    It is a required field that lists the postal address of the physical store where a product is available, used for local inventory ads and free local product listings.
  2. Is store_address different from store_code?
    Yes. store_code links a product to a specific store listed in your Google Business Profile. store_address separately states that store’s postal address. Most local inventory feeds need both to be accurate.
  3. Do I need store_address if I only sell online?
    No. Google’s own troubleshooting guidance says online-only businesses should remove the local inventory ads and free local listings add-ons rather than try to satisfy an address requirement that doesn’t apply.
  4. What is the new warranty attribute in Merchant Center?
    It’s a product feed attribute that states a product’s warranty length, now required for products that need warranty disclosure under Quebec’s Bill 29 in Canada. It remains optional for products outside that requirement.
  5. Does the warranty attribute apply to Indian merchants?
    Not currently. It is tied specifically to Quebec, Canada’s consumer protection law. It would only matter to an India-based business advertising products for sale into Canada.
  6. When will the warranty duration actually show on Shopping ads?
    Google has only said display “will begin later this year,” without a specific date, as of this writing.
  7. What happens if my feed is missing a required attribute?
    Google’s documentation states that non-compliant products are disapproved, and Merchant Center flags them in your account — meaning those products stop showing in Shopping ads and free listings.
  8. Why are local inventory ads suddenly relevant to more advertisers?
    Since late August 2026, Shopping campaigns linked to Merchant Center accounts with the local inventory add-on have had local inventory ads enabled by default, pulling in advertisers who may not have actively opted in.
  9. How do I check if my store_address data is correct?
    Confirm it exactly matches the address on your verified Google Business Profile — same spelling and formatting — for every store location you sell from.
  10. Should I wait for a disapproval notice before fixing this?
    No. Several of these requirements have no published grace period or deadline, so it’s safer to audit and fix proactively rather than wait for enforcement.
  11. Will more countries get warranty-style mandatory attributes like Quebec’s?
    Google hasn’t announced this. It’s a reasonable pattern to watch — Google has been adding region-specific compliance fields to its global feed spec — but no such requirement for India currently exists.
  12. Where can I verify these requirements myself?
    Directly on Google’s Merchant Center Help pages for store_address and the product data specification, since Google can update these fields without much advance notice.
