Access to contact details
Confirm that you can currently open the email or phone channel you intend to use.
When a registration request appears, check the address and identity first. Similar names do not establish that two domains share an operator. A familiar address is preferable to an unfamiliar shortened link.
Use contact details that you control. Someone else's phone or email can make later verification or recovery difficult. If a form requests information for an unclear purpose, read its explanation before supplying it.
Account creation and identity verification are different outcomes. Read the success message, applicable terms and next instruction separately. Resubmitting without understanding the result can duplicate a request.
Read the complete browser address and stop entering details if the destination is unfamiliar.
Have your own contact information and a new, unique password ready.
Distinguish success, a pending state and an error before deciding what to do next.
Store relevant confirmation details securely and read the purpose of any further verification.
Consider these situations separately before deciding how to proceed.
Confirm that you can currently open the email or phone channel you intend to use.
Understand age, applicable conditions and information use before giving consent.
Avoid reusing another site's password; a reputable password manager can help store a unique one.

If a field shows an error, read the instruction beside that field. Check spelling, unintended spaces and the selected country code. Changing every value at once makes it harder to isolate the cause.
If a code does not arrive, check the contact spelling and the waiting instruction. Avoid repeated requests in quick succession. Never give a code to an unfamiliar person; the help page explains how to prepare a focused problem report.
This is a registration explanation. Submitting information here does not create an account.
Use a contact channel you control; borrowed details can prevent later access.
Inspect the error text and relevant fields before sending the same request again.
Do not send identity documents in unsolicited email. Verify the destination and purpose of any document request.
