The street is familiar, so you accept the browser’s suggestion. Only on the order summary do you notice the old apartment number. Autofill can save a lot of typing while still filling in a perfectly plausible wrong address.
There are three places to review: the saved suggestion, the form currently on screen and the address held by the shop. Correcting one is not proof that all three changed.
Fix the saved suggestion
In current Chrome on a computer, open More → Passwords and autofill, then the category containing your address or contact details. Use the entry’s menu to edit or delete it. Labels and available features can differ by version and region.
Check the full entry before removing anything. Two similar addresses may represent home and a collection point rather than a duplicate. Google notes that edits made while signed in to Chrome can also appear on other devices using the same account.
Read the completed form again
After choosing a suggestion, check country, city, postal code, house and apartment numbers, recipient and phone. A website may split address lines differently from the saved record. Put a building or apartment detail into the field the site actually expects.
Then inspect the final order summary and the shop’s own address book. Editing Chrome does not, by itself, revise an order already placed. If you discover an error after submission, use that shop’s order-management process promptly. Do not assume that changing autofill will redirect a parcel already being prepared.
