We encourage sellers to check their business tools – such as spreadsheets, letter and label templates, etc. – to make sure they can handle item numbers that are up to 19 digits. If you use specialised software applications for listing and managing item data, please check with your developer to make sure they can support item numbers up to 19 digits.

	***Original: Coming Soon: Item Numbers Expanding***
	17 May 2006 | 06:37PM EST To ensure the site can accommodate a growing number of listings, we will soon increase the number of digits included in our item numbers. Current item numbers will not be impacted, but after this change, all new listings will have item numbers in the 12-digit range. These digits may increase over time to up to 19 to support future growth. Regards, The eBay Team
