A Terminal ID (TID) is a unique eight-digit code that identifies your payment terminal. When customers pay electronically, this code tracks the transaction through the payment network. TIDs follow RBI regulations and play a crucial role across payment systems, including UPI, RuPay, and payment gateways like Razorpay.

What is a Terminal ID Number?
A terminal identification number is a unique identifier that shows where a payment came from. When your customer pays at your store, the TID tells payment processors exactly which terminal handled the transaction. This matters for your business because it creates a clear trail for every sale.
If you run a large retail chain in India, TIDs help you track sales across all your locations. Each store might have several terminals, and each one has its own TID. This system lets you see which branches perform best and spot issues with specific machines.
A bank or payment aggregator assigns TIDs when you set up payment services. Companies like Razorpay or PayU provide these codes for both physical and online terminals. When managing multiple terminals, the TID becomes crucial for tax filing. You’ll need to reconcile transactions from all your TIDs when preparing GST returns or during financial audits.

Real-world example |
An Indian clothing retailer with stores in Delhi and Mumbai has different TIDs for each location’s payment devices. |
The same retailer has one MID that connects all store locations to their bank account. |
Your TID shows which specific device handled the transaction, while your MID ensures the money reaches your business account. If you run an online marketplace with warehouses in multiple cities, each fulfillment center might use different terminals (TIDs) while operating under your single company identifier (MID).
What’s the Purpose of a Terminal ID Number?
1. Transaction Tracking
A TID number tracks every transaction that passes through your payment device. It serves as a digital fingerprint that connects each payment to its specific terminal.
2. Multiple Terminal Management
For businesses with multiple payment machines, TIDs help manage all terminals under one merchant account smoothly.
3. Dispute Resolution
When issues arise, your TID proves invaluable. It helps resolve chargeback disputes by pinpointing exactly where a transaction occurred.
4. Payment Routing
Banks and payment networks use this identifier to route funds correctly through the complex payment ecosystem. This becomes important when investigating potential fraud cases.
5. Tax Compliance
TIDs also connect to your GST invoicing system, streamlining tax compliance.
6. Regulatory Compliance
The Reserve Bank of India mandates TIDs as part of its digital payment security guidelines. This makes them essential for regulatory compliance.
How to Find Your Terminal ID Number?
On most POS terminals, you’ll find the TID by accessing the settings menu and looking for device information or terminal details. Many payment terminals also print the Terminal ID on receipts, usually near the top or bottom of the slip.
If you use a mobile payment app, you can typically locate your TID in the account settings or merchant profile section. Your payment processor or acquiring bank can also quickly provide this information when you contact their customer support team. Terminal manuals also contain specific instructions for locating your TID, so check these resources first.
For Indian merchants, you can retrieve your Terminal ID through your RBI-approved POS provider’s merchant portal or by calling their dedicated support line. Major Indian payment gateways also display merchant Terminal ID on dashboards under account details or terminal management sections.
Are Terminal ID Numbers Secure?
Each TID is unique to your specific terminal and impossible to duplicate. This security design helps track your transactions accurately and significantly reduces fraud risk. When you process payments, your TID is encrypted, protecting sensitive data as it travels between systems.
Payment processors and banks implement robust security protocols that safeguard your TID during transaction processing. These measures align with the RBI’s strict digital payment security guidelines for POS terminals.
TID also plays a crucial role in fraud detection across the payment ecosystem. When unusual activity occurs, authorities can trace transactions to specific terminals. This makes it easier to investigate issues and resolve chargebacks.
While your Terminal ID offers strong protection, you should still follow security best practices. Keep your payment terminals updated, use secure networks, and limit TID access to trusted staff members only.
Is There a Link Between Terminal IDs and Chargebacks?
TIDs play a crucial role in the chargeback process, even though they don’t directly cause disputes. When a customer files a chargeback, TID helps trace exactly where the transaction occurred. This tracking ability lets you quickly identify patterns of fraud or technical issues at particular points of sale.
Under NPCI and RBI regulations, merchants must maintain proper TID records for all transactions. These records are essential when investigating disputed payments. For UPI transactions, the TID links digital payments to specific virtual terminals, while RuPay disputes rely on TIDs to verify transaction legitimacy.
