There is no fixed upper limit on the number of products that can be listed in an eBay personal store. This number mainly depends on multiple factors, such as the seller's account type, sales performance, and eBay's policies.

For entry-level personal sellers, eBay usually sets a relatively low product listing limit, which is to ensure the quality and stability of the platform. As sellers gradually accumulate sales experience on eBay and their sales performance is recognized, this limit will be increased accordingly.

eBay will also adjust the number of products listed based on the seller's account performance, such as buyer reviews, return rates and other factors. If the seller's account performs well, then they may be able to get a higher listing limit.

Therefore, for sellers who want to sell a large number of products on eBay, it is crucial to improve account performance and increase buyer satisfaction.

Sellers also need to comply with eBay's regulations, ensure that the products they sell are legal and compliant, and avoid infringement or duplicate listings to maintain good store operations and reputation.

In general, how many products can be listed on eBay personal stores is a dynamic process, which depends on the seller's performance and the platform's policies. Sellers should strive to improve sales performance and account performance to obtain higher listing quantity limits, and comply with platform regulations during operations to ensure the steady development of the store.

eBay's policies and regulations may change over time, so it is recommended that sellers regularly check eBay's latest policies to ensure compliance with store operations.
