Your contacts' data is one of your most important assets, so you want to be able to keep it up to date and accurate. If you need to update or edit the data you hold for an individual contact, you can do this in the Single customer view.
Before you start
You can change a contact's Email or Mobile number even if they're unsubscribed or suppressed.

Go to Audience > Contacts.

Change a contact's email address or mobile number
You can change a contact's email address or mobile number in their Single customer view, whatever their subscription status. The new email address or mobile number keeps the status of the one it replaces, so changing it doesn't resubscribe the contact.
For example, if a contact's email address is unsubscribed and you change it, the new email address is unsubscribed too.
There are some exceptions:
Email addresses suppressed for a system reason
If the old email address was suppressed for a reason such as a spam trap, the new email address has the status Suppressed by you.Bounced mobile numbers
If the old mobile number bounced, the new mobile number has the status Suppressed by you.Contacts who haven't confirmed their subscription
If the contact hasn't confirmed their subscription yet, we send a confirmation email to the new email address. Confirmations sent to the old email address no longer count.
You can't change an email address or mobile number to one that:
is on the Global Suppression List with a mandatory suppression
belongs to an email domain you've suppressed
another contact in your account already uses
Using our API?
You can also change a contact's email address or mobile number using API v3. The same rules apply.

Mobile number ID field
Marketing uses mobilenumberid as the default field for mobile numbers.
This field is a unique identifier, like email, and is not listed among custom data fields but appears during import mapping and in signup forms.
To collect mobile numbers for SMS, use the default mobilenumberid field. Do not create a custom field for this purpose.
