Yes. Under your name in the top right, choose Edit Account Details. You can change your name, company name, address, phone number and email address there.
Do it before the next invoice, not after
These details are printed on every invoice at the moment it is generated. Correcting them now changes future invoices; it does not retroactively correct ones already issued. If your registered company name, address or tax identifier is wrong, fix it before your financial year end rather than during the audit — and if historical invoices need correcting, tell us which ones and what they should say.
Your address also determines how tax is calculated, where tax applies. It is the account address that matters, not the billing address stored with your card.
Changing the email address changes your login
The primary email address is what you log in with, and it is where password resets are sent. If you change it, make sure the new address works before you log out.
The trap worth avoiding
Do not let the only address on your account be a mailbox on the very domain that account controls. If the domain expires or the hosting is suspended, that mailbox stops working — and every notice warning you about it was sent there. Keep at least one contact on a completely different domain and provider.
Changing other people's details
Additional people on the account are managed under Contacts, not here. Editing your own account details does not change theirs. This is also where you control which notification types each person receives — a billing contact who gets invoices but not technical alerts is a common and sensible split.
Domain contact details are separate
The registrant details attached to a domain are held at the registry and are not the same record as your portal account. Changing one does not change the other. Domain registrant contact details are edited on the domain's own management page — and note that changing them can trigger a 60-day transfer lock at some registrars.
Worth a yearly review
Once a year, check every address and phone number on the account, including the ones used for two-factor. Ten minutes then saves days of account recovery later. The article on keeping recovery details current has a full checklist, including what to do when someone leaves.
