How to call India from Australia in 2026

The dial string is +91 followed by the Indian number with the leading 0 dropped. An Indian mobile printed as 09876 543210 is dialled as +91 98765 43210. A Mumbai landline printed as 022 1234 5678 is dialled as +91 22 1234 5678. Indian 1800 toll-free numbers do not connect from Australia.

The dial string

To call India from Australia:

• ›+91 {STD or mobile} {number}, or
• ›0011 91 {STD or mobile} {number} from an Australian landline that still wants the international access prefix.

0011 is the Australian equivalent of the 00 prefix used in Europe. Drop the leading 0 from the Indian national number. Corridor landing: call India. Format: India calling codes. Origin context: call Australia.

Mumbai uses 22. Delhi uses 11. Bangalore / Bengaluru uses 80. Do not keep a domestic 0 after +91.

TRAI is the Indian regulator. The ITU E.164 list is the international reference. Australian government context: Smartraveller India.

Mobile vs landline

Indian mobiles are 10 digits starting 6, 7, 8, or 9 after +91. Airtel, Jio, Vi, and BSNL all sit on those ranges with portability. The prefix is a hint, not a guarantee of the current network.

Geographic landlines use 2-4 digit STD codes plus a subscriber number that brings the national significant number to 10 digits after dropping the trunk 0. Examples: Mumbai +91 22, Delhi +91 11, Bangalore +91 80, Hyderabad +91 40, Chennai +91 44.

India does not bill the receiver for a normal incoming international call on a normal mobile or landline.

What it costs

Four realistic routes for an Australia to India call in August 2026:

• ›Australian mobile with no add-on. Telstra and other major carriers publish international pay-per-minute rates that are measured in dollars per minute for India without an international pack (Telstra call overseas). Confirm the current India rate in the carrier app before a long HDFC or Income Tax hold.
• ›International calling pack. Optus, Telstra, and Vodafone AU packs often cut India rates sharply versus bare pay-as-you-go. If the pack names India, the handset can win on short calls.
• ›Pre-paid calling card. Cards aimed at Australia to India traffic advertise low headline rates. Connection fees and mobile surcharges raise the effective price on short calls.
• ›Browser-to-phone. Live rates to Indian mobiles start from $0.06/min and landlines from $0.05/min, billed per minute, rounded up, no connection fee.

If India is already in an Australian international pack at a low rate, use the handset. If it is not, browser-to-phone is usually cheaper for a 20-40 minute bank queue. How calling works: how it works.

Toll-free numbers from this corridor

Indian toll-free numbers start 1800 or 1860. They are domestic. From an Australian number the call fails.

Banks and agencies that print 1800 also publish a paid STD landline. HDFC international-facing contacts are on HDFC Bank from abroad. Prefer +91 22 … or the paid city line on the same page.

Best calling windows

India uses IST (UTC+5:30) year-round and does not observe DST. Australia spans multiple zones. From Sydney / Melbourne (AEST, UTC+10; AEDT UTC+11 in summer), India is 4.5 hours behind in Australian winter and 5.5 hours behind in Australian summer.

Indian banks and government offices do not publish quietest-hour data, so this guide does not guess one. Work from the opening hours on the contact page for the line you need. Indian late morning, 10:00-13:00 IST, is 14:30-17:30 AEST or 15:30-18:30 AEDT, so it lands in the Australian afternoon rather than late at night.

Many offices break for lunch around 13:00-14:30 IST, and public lines often wind down in the last hour before closing. Expect reduced cover on the first working day after an Indian public holiday.

Pitfalls specific to this corridor

• ›1800 vs STD. Letters that show only 1800 are incomplete for Australian callers. Find the paid STD line.
• ›Keeping 022 after +91. Mumbai must become +91 22, not +91 022.
• ›DTMF on deep IVRs. Many Indian bank menus are 4-6 levels deep and ignore dirty keypad tones. Test one digit early; redial if the menu restarts.
• ›OTP on an Indian mobile. Banks send SMS to a registered 10-digit Indian SIM. A password reset from Australia stops if that handset is offline in India.
• ›Time-zone math errors. IST is half an hour off whole-hour zones. Confirm 10:00 IST against the local Australian clock before dialling.

Quick checklist

• ›Have the destination as +91 plus the national number without the leading 0.
• ›Mumbai landlines: +91 22, not +91 022.
• ›Aim for 10:00-13:00 IST.
• ›Have account numbers and a reachable Indian mobile for OTP.
• ›Skip 1800; use the paid STD line.
