Overview

Error 8571 appears when a seller reaches the weekly ceiling for creating brand‑new ASINs. The restriction resets each Sunday at 00:00 GMT, and it exists to protect catalog quality. Sellers who understand the cap and plan around it can keep product launches on schedule.

Key Points

• Weekly ASIN ceiling — Every seller account is assigned a rolling limit on the number of fresh ASINs it may generate; the counter empties at 00:00 GMT on Sunday.
• Tighter caps for new accounts — Accounts opened within the past few months start with a lower allowance, which automatically climbs as sales history builds.
• Even veterans can be throttled — A seasoned seller who attempts to upload a large batch of new listings in a short span can still trigger the limit temporarily.
• Existing ASINs are exempt — Adding offers to products that already have an Amazon ASIN does not count against the weekly quota.
• Goal is catalog integrity — The limit helps prevent duplicate, incomplete, or misleading product pages that could erode buyer trust.
• Bulk uploads consume the quota quickly — Using flat‑file or API bulk‑load tools can exhaust a week’s allowance in minutes if the file contains many new ASINs.

How to Resolve Error 8571

1. Wait for the weekly reset — The simplest remedy is to pause new‑ASIN creation until Sunday 00:00 GMT, when the counter returns to zero. For example, a seller who used all 30 allowed ASINs on Thursday can resume creating new listings the following Sunday.
2. Leverage existing catalog entries — Search Amazon’s database before generating a new ASIN; if a matching product exists, attach your offer to that listing. A private‑label seller who discovers an identical SKU already listed can avoid using a quota slot and benefit from existing reviews.
3. Prioritize high‑impact products — If you must create new ASINs before the reset, focus on items with the greatest revenue potential or time‑sensitive launch dates. For instance, a seller rolling out a seasonal gadget should allocate the remaining quota to that product first, postponing lower‑margin accessories.
