Creating an Account

To use the services on the DNC Registry, an organisation/individual will need to apply for a main account on the DNC Registry website. Each organisation/individual will only be allowed to apply for one main account.

For organisations, one or more sub-accounts can also be created under a main account, to allow more than one user in the organisation to perform telephone number checks against the DNC Registry. There will be a one-time account creation fee for each main and sub-account.

Each main account will receive 1000 free credits every year, which will be valid for one year from the date the free credits were given.

There are three types of accounts, for:

1. Organisations registered in Singapore
   To create the account, the organisation’s Unique Entity Number (UEN) and a representative’s CorpPass is required. Please visit www.uen.gov.sg and www.corppass.gov.sg if you do not have them.
2. Overseas organisations not registered or present in Singapore
   To create the account, your company registration information and phone/utility bill are required. A user ID will be issued upon successful application.
3. Any individual who needs to check the DNC Registry
   To create the account, the user’s SingPass is required.

If your organisation is checking the DNC Registry on behalf of another organisation, you should list the name of the organisation(s) you are conducting the checks on behalf of on the declaration page during the account creation process. This list can be amended subsequently.

Upon successful creation of the account, an activation link will be sent to the email address provided. Follow the instructions provided in the email to activate the account.

Checking the Registry

There are three DNC Registers for:

• No Voice Call Register – for phone calls;
• No Text Message Register – for texts including Short Messaging Service (SMS) and Multimedia Messaging Service (MMS); and
• No Fax Message Register – for faxes.

Under the PDPA, your organisation will need to check the relevant Register(s) before sending telemarketing messages. Only 8-digit numbers starting with 3, 6, 8 or 9 will be accepted by the DNC Registry for checking.

At the DNC Registry website, there are two methods to submit telephone numbers for checking:

1. Small Number Lookup
   You may enter up to 10 telephone numbers at a time. Results will be displayed immediately.
2. Bulk Filtering
   You may submit as many telephone numbers as required by uploading a CSV file containing a single column of 8-digit telephone numbers (click here for a sample of the CSV file to be uploaded). Results will be available within 24 hours. An email and/or SMS will be sent to notify you when the results are ready.

The following result files will be available for download:

1. Filtered Numbers – the list of submitted numbers together with their status in each Register. Rejected numbers will not be listed in this file. Click here for a sample file.
2. Summary – a summary of the submission. Click here for a sample file.
3. On Behalf List – the list of organisations that you are checking on behalf of, as at the time of submission. This file will be empty if your On Behalf List is empty. Click here for a sample file.
4. Rejected Numbers – the list of submitted numbers that could not be processed, together with the reason why each number was rejected. This file will be empty if all numbers were processed successfully. Click here for a sample file.

Telephone numbers submitted will be checked against all three DNC Registers. There will be a charge for each number checked, regardless of whether the number has been submitted before. Free credits allocated will always be used first to offset any charges incurred for checking the DNC Registry, followed by purchased credits. 

 
You can purchase credits via the Pre-paid scheme or make payment directly using the Pay-per-use scheme:
