What is a transaction alert SMS?

A transaction alert SMS notifies a customer that money has moved or an account detail changed: a debit, credit, wallet top-up, refund, or a change of password, mobile number or bank details. Banks send these under the DLT transactional category; other businesses use service implicit. Both are delivered at any hour and reach DND numbers.

Questions about SMS transaction alerts

What is the difference between transactional and service implicit alerts?

Under TRAI's DLT rules, the transactional category is for banks' OTPs and account debit or credit alerts, with a -T header suffix. Wallets, NBFCs, merchants and apps send similar alerts as service implicit with a -S suffix. Both go out 24x7 and reach DND numbers.

Can transaction alerts be delivered at night?

Yes. Transactional and service implicit SMS have no time window, so a debit at 2 am is reported at 2 am. The 10 am to 9 pm restriction applies only to promotional messages.

Should transaction alerts show the full account number?

No. Show only the last 4 digits of an account or card number. Full numbers in an SMS can be seen by anyone with the phone and are a fraud risk. Never include PINs, CVVs or passwords.

Can I send transaction alerts through SMPP?

Yes. MsgClub offers SMPP for high-volume senders such as banks and payment companies, alongside the REST API. SMPP keeps a persistent connection open, which suits a steady flow of alerts from a core system.

Can a merchant send payment received alerts?

Yes, as service implicit SMS. Shops, schools and service businesses can confirm a payment received, a refund processed or a wallet credit. Keep the message to the transaction itself, without offers.

Are WhatsApp alerts a replacement for SMS transaction alerts?

Not for banks and payment apps. SMS reaches every registered number without opt-in or data, which is why regulators and customers rely on it for money movements. WhatsApp can add a monthly statement or a richer receipt for customers who opted in.
