# Do Not Call list

> Stop Revenue Recovery calls and proactive texts to specific phone numbers.

The **Do Not Call** page stores phone numbers that hyzl must not contact through Revenue Recovery.

The internal list is always on and free. It applies to recovery calls and proactive recovery texts.

## Find a number

Choose **Do Not Call** under **General**. Enter at least 3 phone-number digits to search the list.

Search matches the start of a stored number. It accepts digits with or without the country code.

The table shows the reason and date for each entry. It lists the newest entries first.

The table shows 25 numbers per page by default. You can change the page size to 50 or 100.

## Add numbers

Choose **Add number** to add one phone number. Add an optional reason that explains the restriction.

Use **Paste a list** to add several numbers. Separate numbers with commas or line breaks.

hyzl skips invalid entries and reports them.

When a member replies STOP, hyzl adds the member's number automatically.

## Revenue Recovery enforcement

hyzl checks the list before each recovery call. A listed number does not receive the call.

hyzl also checks the list before proactive recovery texts. This includes reminders and final recovery messages.

The current recovery becomes parked when the list blocks its call. Removing the number does not restart that recovery.

Removing a number allows future eligible recovery outreach. Leave opt-outs listed unless you have a valid reason to remove them.

<Note>
  This internal list differs from the US National Do Not Call Registry. The
  national registry check is an optional campaign service and does not replace
  your compliance process.
