BSNL Customer Service Number — Complete Practical Guide

Overview and official contacts

Bharat Sanchar Nigam Limited (BSNL) is the government-owned telecommunications company formed in 2000 (incorporated 15 September 2000; operations started 1 October 2000). For any commercial, fault or billing query the authoritative entry point is the BSNL customer service system — phone, web portal or circle customer service centers. The official corporate portal is https://www.bsnl.co.in where circle-wise contact details, service-specific helplines and online complaint forms are published and kept up-to-date.

The single most important fact to remember: if you dial a BSNL helpline from a BSNL number you will usually get a toll-free connection and access to IVR-assisted routing. For non-BSNL lines there are national toll-free numbers and circle helplines; always verify the number for your state/circle on the BSNL website before calling to avoid STD/long-distance charges.

Primary customer service numbers and when to use them

The following numbers are the primary entry points many customers use. These numbers are managed centrally and then routed to your circle (state) helpdesk or to the appropriate business vertical (landline, broadband/FTTH, mobile prepaid/postpaid):

• 1500 — Primary BSNL customer care number (toll-free when called from a BSNL landline or mobile).
• 1800-345-1500 — Alternate national toll‑free number for customers dialing from non-BSNL lines (verify on bsnl.co.in for your circle).
• BSNL website: https://www.bsnl.co.in — Online complaint form, service status, account login and bill payment.

When you call 1500 you will typically first encounter an IVR that asks you to choose the service category (landline, broadband, mobile, enterprise). Keep your account number, telephone or mobile number and any error messages or fault indicators ready. For broadbands/FTTH faults the IVR normally asks for your DSL/FTTH number and will issue a complaint reference number (CRN) that you must note for follow-up.

If you have a circle-specific or enterprise-level account (corporate BSNL), there are dedicated numbers and relationship managers; these are listed on the circle pages on bsnl.co.in. If your issue is billing, service migration, or porting (MNP), mention exact dates and service IDs when you call to speed up resolution.

How to lodge complaints, track and escalate

Best practice for filing and tracking a BSNL complaint: first call the national helpline (1500), register the complaint through IVR or CSR, and obtain the CRN. Immediately after, you can file the same complaint online through the official portal; this creates an electronic record that is useful for escalation. BSNL’s process assigns the complaint to the local exchange/field team and provides an expected closure timeframe — typically 24–72 hours for line/broadband faults depending on severity and parts availability.

If the fault persists beyond the stated SLA, escalate to the circle-level nodal officer. Each circle publishes contact details (nodal officer, AGM/GM offices) on the BSNL website. Keep the CRN, timestamps of prior calls, screenshots of speed tests or error messages, and any SMS/email acknowledgements; these are necessary for faster escalation and for any compensation claims.

• Step 1: Call 1500 → Obtain CRN → Note time and agent ID.
• Step 2: File same complaint online at https://www.bsnl.co.in → Attach supporting documents (speed test, photo).
• Step 3: If unresolved past SLA, escalate to Circle Nodal Officer (details on circle page) and request higher-level CRS or SMS escalation.

Head office, circle offices and official resources

BSNL’s corporate headquarters is located in New Delhi; the commonly used address for corporate communications is Bharat Sanchar Bhawan, Janpath, New Delhi — PIN 110001. For legal, corporate and central grievances you may refer to the headquarters address listed on bsnl.co.in. Each state and union territory operates a BSNL circle with its own office, customer service centers (CSCs) and appointed nodal officers — these must be consulted for localized issues like technician visits, new FTTH provisioning or right-of-way permissions.

For reliable, up-to-date information use the official portals: the main site https://www.bsnl.co.in, the online complaint portal within that site, and the “My BSNL” mobile app (available on Google Play and Apple App Store). These channels show your billing history, plan details, recharge options and active complaints, and they provide secure e-payment options (UPI, net banking, debit/credit cards).

Practical tips, timings, and expectations

Prepare before you call: have your customer account number, registered mobile number, installed device serial numbers (ONT/Router), and past bill copies. For broadband speed/fault complaints, run a speedtest (record time, server, download/upload results) and include a screenshot when filing the complaint. Typical technician visit windows are 9:00–18:00 local time; if you need an emergency resolution (e.g., to restore business connectivity) instruct the agent to mark the issue as “priority” and ask for an expected time of arrival.

Charges: calls to 1500 from BSNL numbers are usually free. Online complaint filing and status checks are free. Installation, migration and certain value-added services may have fees — verify the exact charges at the time of request on the website or through the agent. For persistent unresolved issues, you can escalate to the Telecom Regulatory Authority (TRAI) grievance portal or approach consumer court after exhausting BSNL’s escalation hierarchy.
