hello if i buy a cable charger in walmart an i would like to register my item with anker where i can find the order number in my receipt or the box of my item
Could you expand on what you mean by this? Does anker want the products number?
If you have any issue, you can reach out to Anker Support.
If you want to check if you need to register your device or cable just for support, answer is you DON’T need to register. To report it, within the return period, you can give it back to Walmart. After the return period, you can contact Anker Support along with the purchase proof ( scan copy of receipt) and they will provide the resolution as feasible per policy.
You should just call Walmart and give them the receipt ID, they might be able to help.
