What to check before paying by UPI
When you scan a merchant’s QR code, pause at the payment screen before authorizing anything. NPCI says merchant information is stored in the QR and shown to the customer on the payment page. Check the payee or merchant information against the business you intend to pay, then check the amount. These are separate checks: a familiar-looking amount does not confirm the payee, and a matching business name does not confirm the amount.

If the payee information does not look right, the amount is unexpected, or the screen is unclear, do not authorize the payment yet. Ask the merchant to clarify or provide a fresh payment request, then review the new details yourself. Do not rely on a verbal assurance instead of checking what your own app displays. If the merchant cannot explain a mismatch, stop and use another way to resolve the payment.

The QR identifies the payee; it does not tell you the full set of information that may be exchanged or visible to the merchant. Treat the payment screen as a chance to verify the transaction, not as proof that your personal details are hidden. NPCI’s UPI FAQ explains the QR payment flow and provides guidance on authorizing transactions.

Can you pay without showing your mobile number?
Possibly, depending on the UPI app and the ID you use—but NPCI’s official guidance does not establish that a payer’s mobile number is always hidden from every merchant. Nor does it establish that a phone number is always exposed. The exact answer can depend on the app, bank, and payment flow, and the cited NPCI materials do not give a universal, field-by-field list of information visible to every merchant or provider.
A mobile-number UPI ID and the phone number associated with an account are not necessarily the same disclosure question. Disabling an ID that contains your number is a specific control over that ID. It is not proof that no phone number or other personal information can be seen elsewhere in a transaction. If you need to know whether a particular detail is visible in your own payment flow, check the privacy information for your UPI app and bank or ask them directly.
BHIM’s documented mobile-number ID control
NPCI says BHIM users who create a secondary UPI ID can enable or disable mobilenumber@upi. NPCI also says the QR for that disabled UPI ID is disabled. This is a documented BHIM feature, not a universal setting for all UPI apps. If you use BHIM, check its current profile privacy controls and confirm which ID is active before paying. The NPCI BHIM product page describes this option.

The distinction matters: the documented control concerns the mobile-number UPI ID. It does not say that all personal information is removed from every payment, that every other UPI ID works the same way, or that merchants cannot see any payer information. Other apps may use different controls, names, or defaults. Check the privacy information and settings for your own app and bank rather than assuming the BHIM option exists elsewhere or changes what information is visible in every kind of transaction.
Steps for a more deliberate merchant payment
- Open an app you trust. Start the payment from your own UPI app, rather than handing your unlocked phone to the merchant or letting someone else operate it. This keeps the payment screen and authorization under your control. It does not by itself establish which information the merchant can see, so continue checking the transaction details.
- Scan the merchant’s QR yourself. Use the QR presented for the payment and read the payee information and amount shown in your app. NPCI says merchant information is stored in the QR and displayed on the payment page. Do not approve the transaction just because you scanned a QR or because the merchant says the details are correct.
- Match the displayed payee to the business. Check the information in the app before authorizing. NPCI’s QR guidance makes the merchant information visible to the customer on the payment page, giving you a chance to catch a mismatch. If the displayed payee is unfamiliar or does not fit the business, pause and ask the merchant to clarify or provide a fresh request.
- Check the amount independently. Confirm that the amount shown is the amount you intend to pay. If it is wrong or unexpected, do not proceed until it is corrected. After a corrected request appears, review the payee and amount again rather than assuming that only the amount changed.
- Use the right UPI ID if your app supports it. In BHIM, if you have created a secondary UPI ID and do not want to use the mobile-number ID, check the profile privacy control for
mobilenumber@upiand disable it if appropriate. NPCI says the QR for that disabled ID is also disabled. This guidance is specific to BHIM; do not assume that another app has the same control, or that disabling the ID hides every other personal detail. - Enter your UPI PIN yourself and keep it private. NPCI says the PIN authorizes bank transactions and states: “Please do not share your UPI-PIN with anyone.” Enter it in your app where practical, away from the merchant’s view. Never tell it to a merchant, caller, or person claiming to help with the payment. A request for your PIN is not a reason to disclose it to someone else.
- For an international merchant, inspect the final amount carefully. If the merchant accepts UPI Global, activate the relevant service if required and review the amount in both currencies, along with applicable exchange rates or fees, before authorizing. NPCI’s UPI Global Acceptance guidance concerns international merchant payments; it should not be assumed to describe a domestic transaction. The guidance supports checking the final amount and applicable conversion details, not assuming a particular rate or fee.
What the merchant’s QR does—and does not—tell you
NPCI’s BHIM UPI guideline, updated June 4, 2026, says a merchant must display the merchant’s own UPI ID below the QR code, with the label “UPI ID.” That is the merchant’s identifier, not the payer’s. Seeing the merchant’s ID can help distinguish the merchant’s displayed payment identifier from your own UPI ID, but it is not evidence about which details of the payer are shared with or visible to that merchant.
If the displayed merchant ID or the payee shown in your app does not fit the business you are paying, pause and ask for clarification rather than relying on the QR alone. The presence of the label “UPI ID” below a QR does not answer the separate privacy question of what information your app or bank makes available during payment. Keep those questions separate: verify the merchant information for transaction accuracy, and consult your provider for a precise explanation of payer-data visibility.

NPCI lists QR, intent, application-based, and collect as UPI merchant integration modes. They describe different ways a merchant payment can be initiated, but the official material cited here does not compare them for payer-data minimization. There is no supported basis here for claiming that one is categorically more private than another. Whichever mode you use, review the details the app presents before approval and consult your app and bank’s privacy information if you need to know exactly what they disclose.
What you can and cannot conclude about privacy
These steps give you control over checking the payee and amount, keeping your PIN confidential, and—in BHIM’s documented case—disabling a mobile-number UPI ID after creating a secondary ID. They do not establish that your name, phone number, or account details are always hidden, nor that those details are always exposed. NPCI’s cited materials do not provide a universal, field-by-field account of what every merchant, payment provider, app, and bank can see.
That limit is important if your reason for asking is specifically “Can I pay by UPI without showing my mobile number?” The BHIM option is relevant if you use BHIM and want to disable the mobile-number UPI ID, but it cannot settle what another app or payment flow may display. A QR payment screen showing merchant information is also not a complete inventory of what the merchant can see. Avoid treating either feature as a guarantee of anonymity.

If a particular disclosure would affect whether you make a payment, check the privacy information for the UPI app and bank you use, or ask them directly about that transaction flow. Ask about the specific detail you care about, such as whether a mobile number or another account-related detail is visible to the merchant. Do not infer the answer from a QR, a secondary UPI ID, or a payment confirmation screen alone.

Check your own app and bank for the specific payment flow.
How do I check a UPI QR payment before I authorize it?
Scan the merchant’s QR in your own app and review the payee information and amount shown on the payment page. NPCI says merchant information is stored in the QR and displayed there. If anything is wrong or unclear, pause and ask the merchant to clarify or provide a fresh request.

Does disabling mobilenumber@upi in BHIM hide all my personal details?
NPCI documents this as a control for the mobile-number UPI ID. It does not say that disabling it hides every personal detail in every payment flow. NPCI also says the QR for the disabled ID is disabled.
Is a merchant’s UPI ID below a QR the payer’s ID?
No. NPCI’s BHIM UPI guideline, updated June 4, 2026, says merchants must display their own UPI ID below the QR with the label “UPI ID.” That identifies the merchant; it does not tell you what payer information the merchant can see.
Is QR payment more private than intent, application-based, or collect payment?
The cited NPCI material lists QR, intent, application-based, and collect merchant integration modes but does not compare them for payer-data minimization. It does not support calling one categorically more private. Review the details your app presents and check your app and bank’s privacy information.
Should I tell the merchant my UPI PIN if they are helping me pay?
No. NPCI’s UPI FAQ says, “Please do not share your UPI-PIN with anyone,” and explains that the PIN authorizes bank transactions. Enter it yourself in your own app and keep it private.
What should I check when paying an international merchant with UPI Global?
If the merchant accepts UPI Global, activate the service if required and review the final amount in both currencies, plus any applicable exchange rates or fees. NPCI’s UPI Global guidance concerns international merchant payments and should not be assumed to describe a domestic payment.
The Bottom Line
Scan and review the merchant’s QR payment screen yourself, verify the payee and amount, and keep your UPI PIN private. BHIM documents a way to disable its mobile-number UPI ID after creating a secondary ID, but neither that control nor a QR payment guarantees anonymity. For the exact payer details visible in your transaction, check your own app and bank’s privacy information.
