How to Update Your
Details on GAMSTOP

Why current GAMSTOP details
matter

GAMSTOP uses the registration information attached to a
self-exclusion to help participating gambling operators identify
matching accounts. Its current terms say that inaccurate or outdated
information can make the exclusion less effective.

If your email address, mobile number, postal address or name changes,
update the registration rather than assuming the old details will
continue to match every account. This is an account-maintenance step,
not a way to shorten or deactivate a minimum exclusion period.

This independent guide is not affiliated with GAMSTOP. Use the live
GAMSTOP account and contact routes for any change.

Which details can be
updated online?

GAMSTOP’s help centre says you can sign in to your account to add
information such as:

• a new email address;
• a new postal address; or
• a new mobile number.

The wording is important: keep relevant old details as well as adding
current ones when the account permits it. GAMSTOP’s terms refer to
mobile numbers and email addresses you use or have used with gambling
operators. Removing historic identifiers without official guidance could
reduce the information available for matching.

Sign in only through the official GAMSTOP website. Avoid account
links received from an unverified source.

What if your name has
changed?

GAMSTOP’s current help article says to contact the service to add a
new first name or last name. It says proof of the change will be needed
and gives a marriage certificate or deed poll as examples.

Do not assume those examples are an exhaustive list or send documents
before GAMSTOP tells you what is required and how to provide it
securely. Use the official Contact Centre details published by
GAMSTOP.

What if you cannot
access your account?

If you cannot sign in, GAMSTOP says to contact the service. The
current Terms of Use list the Contact Centre telephone number as 0800
138 6518 and the email address as helpdesk@gamstop.co.uk.

Before sharing personal information, confirm the contact details on
the live GAMSTOP contact
page. Explain which information has changed and that you cannot
access the account. Follow the identity and security steps GAMSTOP gives
you; do not send more information than requested.

Details worth
reviewing after a life change

Review your GAMSTOP account when any identifier used with gambling
operators changes. That can include:

• a move to a new home;
• a new or additional email address;
• a new or additional mobile number;
• a legal name change; or
• loss of access to the primary email or phone linked to the
  account.

GAMSTOP’s Terms of Use say registration information should be
truthful, accurate and consistent with the information used to access
online gambling services. They also place responsibility on the
registered person to keep it current.

Updating details
does not end self-exclusion

Changing account information does not deactivate a GAMSTOP exclusion.
The minimum exclusion period remains in place under the terms selected
at registration. During that minimum period, GAMSTOP says the exclusion
cannot be deactivated.

When a minimum period ends, protection does not simply disappear. A
separate deactivation process applies. Our guide explains what
happens when your GAMSTOP minimum exclusion period ends.

Do not change contact information to try to create an unmatched
gambling account. That would work against the purpose of self-exclusion
and may make it harder for the system to identify accounts associated
with you.

Check the update was
recorded

After following the official process:

1. Sign back in through the official site.
2. Review the identifiers shown on the account.
3. Keep any confirmation GAMSTOP provides.
4. Contact the service if the updated detail is missing or
   incorrect.

Do not publish or share account screenshots that reveal personal
information. If a gambling operator still allows access after your
details are current, record what happened and contact GAMSTOP through
its official support route.

Keep reminders and
account access secure

GAMSTOP’s terms say people can opt in to reminder emails about
keeping registration information updated. A reminder can be useful, but
treat unexpected messages cautiously. Navigate to the official site
yourself instead of entering credentials after following a link you do
not trust.

Use a private email account and phone number you control. Do not
share sign-in details with another person or ask someone else to alter
the registration for you.

Quick update checklist

• Use only the official GAMSTOP website or Contact Centre.
• Add current email addresses, postal addresses and mobile numbers
  through the account when possible.
• Contact GAMSTOP for a first-name or last-name change.
• Ask GAMSTOP what evidence and secure route it requires.
• Contact the service if you cannot access your account.
• Review the saved details after the change.
• Keep confirmation without exposing personal information.
• Remember that updating details does not cancel the minimum exclusion
  period.

Keeping identifiers current supports the matching process that makes
self-exclusion work. If gambling is causing harm or you need additional
support, the National
Gambling Helpline offers free help.
