Check Number Porting Status

Last checked: 26 June 2026

If you need to check number porting status, start by confirming whether your number still has signal, whether you received a porting SMS, and which network is handling the move. In South Africa, number portability lets you keep your mobile number when moving between networks, but a pending, failed, or unauthorised port must be handled through the relevant network’s official support channel. ICASA explains that number portability allows subscribers to keep their number when changing network operator, and says only mobile and geographic numbers can currently be ported. (icasa.org.za)

There is a public number-portability query for South African numbers, but it should be treated as a routing check, not as a full customer-care status tracker. The Number Portability Company offers number-porting services and links to a “check if a number is ported” facility, while the public CRDB query asks users to enter the telephone number they want to query. (number-portability.co.za)

If your number lost signal suddenly, or you received a porting message you did not request, treat it as urgent. ICASA warns that SIM-swap fraud and illegal mobile number porting involve criminals gaining access to a consumer’s mobile number, and advises users to contact their service provider immediately if they lose signal permanently.

Quick Support Route

Use this quick route before trying random codes or replying to unknown messages.

Your situation	What to do next
You requested a port and are waiting	Check the SMS from the new network, then contact the network you are moving to if the port is delayed or declined.
Your old SIM suddenly has no signal	Contact your current network immediately and ask whether a SIM swap or port request is active.
You received a porting OTP or approval SMS you did not request	Do not approve it. Contact your network through official customer care and ask them to block or investigate the request.
Your banking OTPs stopped arriving	Contact your bank through its official app, card number, or branch route, then contact your mobile network.
You want to see whether a number has already ported	Use the public number-portability query as a supporting check, then confirm with the relevant network if service is affected.
Customer care cannot resolve it	Ask for a reference number and follow the provider’s complaints process before escalating to ICASA.

Do not rely on a social media post, forwarded SMS, or stranger’s instruction for a number porting code. A porting request affects control of your mobile number, and that number may be linked to banking, WhatsApp, email, and account recovery.

For broader account menus, see mobile self-service codes South Africa. If this may be fraud, read SIM swap fraud South Africa before approving anything.

What You Need Before You Start

Before you try to check number porting status, collect the details that customer care may need to verify the issue safely.

You may need:

The mobile number being ported.
The network you are leaving.
The network you are moving to.
Whether the number is prepaid, contract, business, or linked to an account holder.
The new SIM serial number if you requested the port.
The date and time you requested or approved the port.
Any SMS confirmation, rejection message, OTP, or reference number.
Proof that you are the legitimate user or account holder, shared only through official provider channels.

Do not share your banking PIN, banking password, app approval, one-time PIN, SIM PIN, PUK code, or remote-access code with anyone who contacts you unexpectedly. ICASA advises consumers not to give consent to unsolicited links, not to provide access to unknown people, and to watch for signal loss as a possible sign of SIM-swap or number-porting fraud. (icasa.org.za)

Warning signs

Take action immediately if:

Your phone suddenly shows “No Service” or emergency calls only.
You receive a porting OTP or approval message you did not request.
Someone calls and asks you to read out a porting code.
You stop receiving banking or account-recovery OTPs.
Your WhatsApp, email, or banking app sends security alerts.
Friends or family receive strange messages from your number.
Your SIM stops receiving calls and SMSs while the phone still works on Wi-Fi.

These signs do not always prove illegal number porting, but they are serious enough to contact your provider immediately.

What not to share

Never share:

Banking PINs or app passwords.
One-time PINs.
SIM PIN or PUK code.
Full card details.
Remote-access app codes.
Self-service login details.
Screenshots that expose OTPs or security codes.
A porting approval code unless you personally started the port and are using the official provider process.

A legitimate support process may ask you to verify your identity, but it should not require your banking password or a one-time PIN for a transaction you did not start.

Provider-by-Provider Options

There is no verified universal USSD code that checks every South African provider’s number porting status. Use the official route for the network involved in the port.

Provider or route	What to use it for
Public number-portability query	Use it to query whether a number has been ported. It is a supporting check, not a replacement for customer care when a port is pending, failed, or disputed. (porting.co.za)
Vodacom	Vodacom’s switching page says prepaid users need a RICA-registered Vodacom SIM and can start a port by SMS using their existing number. If your Vodacom port is delayed or your new SIM does not work after approval, use Vodacom’s official support route. (Vodacom)
MTN	MTN says customers can move to MTN and keep their number. MTN’s eSIM porting terms also refer to porting to licensed networks in South Africa and SMS confirmation for porting steps. Use MTN support if your MTN port is pending, declined, or unclear. (MTN)
Cell C	Cell C’s porting pages describe switching to Cell C while keeping your number and list official switching routes. Use Cell C support if the request was made to Cell C or the Cell C SIM is not activating after the port. (Cell C)
Telkom	Use Telkom’s official app, self-service, store, or support channels to ask about a Telkom-related port. Do not rely on an unverified code for a security-sensitive porting issue.
MVNO or smaller provider	Contact the brand that issued your SIM and ask which network or porting support desk handles the case.

Official verification steps

Follow these steps in order:

Check whether your current SIM still has signal.
Check your SMS inbox for a port request, approval, rejection, or activation message.
Confirm which network is receiving the number.
Contact the receiving network if you requested the port.
Contact your current network immediately if you did not request the port.
Ask for a case or reference number.
Keep screenshots of messages, timestamps, and support replies.
Use the public number-portability query only as a supporting check.
Escalate through the provider’s complaints route if customer care does not resolve it.

ICASA says an approved porting transaction takes a maximum of seven working days from the day the subscriber makes the request, so a long delay should be checked with the network rather than guessed from an unofficial code. (icasa.org.za)

When You Must Contact Customer Care

You must contact customer care directly when the issue involves fraud, identity verification, an account mismatch, a failed port, or a number ported without permission.

Contact your network immediately if:

You did not request the port.
Your SIM suddenly lost signal.
You received a porting OTP you did not expect.
The port was declined and you do not understand why.
Your number is linked to banking, business, email, or WhatsApp.
You cannot receive calls or SMSs after the port should have completed.
The public query suggests the number is no longer where you expected it to be.
Someone is pressuring you to approve a porting request.

Ask customer care:

Is there an active port request on this number?
Which network requested or received the port?
When was the request created?
Was the request approved, rejected, cancelled, or completed?
Was an OTP or approval message sent?
Can the port be stopped or investigated?
What is the case reference number?
What documents are needed to prove ownership or account authority?

For official provider routes, use mobile network customer care numbers. If your phone was stolen or your SIM is at risk, follow block lost SIM South Africa.

What to do if affected

If you believe your number was ported without permission:

Contact your mobile network through official customer care.
Ask them to check for an unauthorised port request or SIM change.
Ask for the request date, status, and reference number.
Contact your bank immediately if the number receives banking OTPs.
Change passwords for important accounts once you regain secure access.
Save SMSs, screenshots, call logs, emails, and case numbers.
Submit a formal complaint to the provider if the matter is not resolved.
Escalate to ICASA if the provider does not resolve the complaint through its process.

ICASA’s complaints procedure includes mobile-number portability complaints and says complaints must first be lodged with the service provider, with ICASA escalation available if the matter is not resolved through the provider’s process. (icasa.org.za)

FAQ

What is check number porting status used for?

It is used to check whether a mobile number is still with the expected network, whether a port request may have completed, or whether a porting issue needs customer-care support. It is especially important if your SIM loses signal, a port is delayed, or you suspect your number was ported without permission.

What is the code for check number porting status?

There is no single verified universal USSD code for checking every South African number porting status. Use the official route for your provider, the receiving network’s support channel, or the public number-portability query as a supporting check. Do not trust a code unless it appears on an official provider page.

Does this USSD code need airtime or data?

It depends on the provider and the channel. Some porting actions use SMS, some use apps or WhatsApp, and some require customer care or a store visit. MTN’s eSIM porting terms mention normal SMS rates for an SMS porting step, so costs and availability should be checked with the relevant provider before use. (MTN)

What should I do if the code does not work?

Do not keep retrying blindly. Check signal, confirm the SIM is active and RICA-registered, review any SMS messages, and contact the receiving network if you started the port. If you did not start the port, contact your current network immediately and ask for a fraud or porting investigation.

What should I do if my number was ported without permission?

Contact your mobile network immediately, ask them to investigate the unauthorised port, and request a case number. Then contact your bank if the number receives banking OTPs. Save all evidence and escalate through the provider’s complaints process if the issue is not resolved.

Can I check number porting status online?

You can use the public number-portability query to check whether a number appears to be ported, but it should not replace customer care for pending, failed, or suspicious cases. If your service is affected, contact the provider directly.

How long does number porting take in South Africa?

ICASA says an approved porting transaction takes a maximum of seven working days from the day the request is made. Individual providers may give more specific timelines for their own prepaid, contract, SMS, app, or store processes, so always check the network handling your port. (icasa.org.za)

Where can I find related USSD codes?

Start with mobile self-service codes South Africa for general provider menus. If you need help with a delayed, failed, or suspicious port, use mobile network customer care numbers instead of trying random codes.
