I have an ASIN that i created very long ago when ii was starting off and did not put in the EAN number.

Is it possible to add an EAN number now that i have GS1 Numbers available?

Please provide a guided answer.

Thanks and happy selling

Hi - we have a new product with its new barcode number which consequently is barred from being added as inventory etc.. The following info was been asked for to send to Customer Service, but I am finding it hard to see any way to contact by email. Any ideas? Thanks, Richard.

Product Name Manufacturer name Brand nameU PC, EAN, ISBN or JAN along with GS1 certificate Non-brand owners: A copy of a letter/email from the manufacturer or brand stating that the UPC, EAN, ISBN or JAN that you are using to list this product is validBrand owner: Valid and current (not expired) GS1 certificate for the GTIN range(s) used by your listings

HI everyone,

Lately some of my listing, suddenly the ean-barcode number has gone missing- not recognized by amazon.

This is the message I get when trying to send items:

"This product is ineligible for sending to Amazon with a manufacturer barcode. Please remove the product from the shipment, re-create the offer with an Amazon barcode and label your units."

All are gs1 brought barcode.

Any advise?
