PIN to PIN Distance Calculator (Exact KM & Delivery Days)

Q: What is the Speed Post delivery standard based on distance in India?

Official India Post norms prescribe: Local / Intra-city (up to 50 km) delivered in 1–2 business days; up to 200 km in 2–3 days; 201 to 1000 km in 2–4 days; 1001 to 2000 km in 3–5 days; and distances exceeding 2000 km in 4–6 business days.

Direct Answer • Official Postal & Highway Coordinates

PIN to PIN distance is the measured transit and geographic distance between any two 6-digit Postal Index Numbers in India. Straight-line map distance is computed using the Great-Circle Haversine formula from official India Post coordinates, while driving road transit applies an industry-standard 1.20× to 1.25× national highway routing factor. This calculation is used nationwide for Speed Post tariffs, courier delivery SLAs (Delhivery, Blue Dart), and GST E-Way Bill validity periods under Rule 138 of the CGST Rules.

Formula: Haversine Great-Circle
Road Factor: +20% to +25% highway curvature
E-Way Bill Slab: 1 Day per 200 km (Normal Cargo)
Coverage: 155,000+ PIN Codes across all 36 States

Official statutory validity periods for goods consignment under the Goods and Services Tax (GST) e-Way Bill system.

CGST Rule 138(10)

Distance in KM	Normal Cargo Validity	Over Dimensional Cargo (ODC)	India Post Delivery Norm
Up to 50 km (Intra-City)	1 Day	1 Day (up to 20 km)	1 – 2 Business Days
51 to 200 km	1 Day	1 Day per 20 km	2 – 3 Business Days
201 to 400 km	2 Days	11 – 20 Days	2 – 4 Business Days
401 to 600 km	3 Days	21 – 30 Days	2 – 4 Business Days
601 to 800 km	4 Days	31 – 40 Days	2 – 4 Business Days
801 to 1,000 km	5 Days	41 – 50 Days	2 – 4 Business Days
1,001 to 2,000 km	6 – 10 Days	51 – 100 Days	3 – 5 Business Days
Above 2,000 km	+1 Day per 200 km	+1 Day per 20 km	4 – 6 Business Days

Note: As per the Central Goods and Services Tax Rules, the validity of an e-way bill is calculated from the time at which the e-way bill has been generated and each day is counted as the period ending at midnight of the day immediately following the date of generation.

Frequently Asked Questions on PIN to PIN Distance

How do I check PIN to PIN distance in KM?

Enter the 6-digit Origin PIN code and Destination PIN code into our calculator and click Calculate. The tool immediately provides the exact aerial distance in kilometers (computed using the Haversine formula from official India Post coordinates) and the estimated road highway distance (~1.25x road factor).

How is PIN to PIN distance used for GST E-Way Bill generation?

Under Rule 138 of the CGST Rules, the validity of an electronic E-Way Bill depends directly on the distance between the supplier and recipient PIN codes. Normal cargo is granted 1 day validity for up to 200 km, and 1 additional day for every 200 km (or part thereof) thereafter. For Over Dimensional Cargo (ODC), validity is 1 day for every 20 km.

Why is road distance longer than aerial map distance?

Straight-line (aerial) distance is the shortest direct geodesic line between two geographic points. Actual road and highway travel is typically 20% to 25% longer due to highway curvature, bypasses, terrain elevations, and road network routing.

What is the Speed Post delivery standard based on distance in India?

Local / Intra-city (up to 50 km) takes 1–2 business days. Up to 200 km takes 2–3 days. 201 to 1000 km takes 2–4 days. 1001 to 2000 km takes 3–5 days, and above 2000 km takes 4–6 business days.

Can I calculate courier distance for private couriers like Delhivery, Blue Dart, and DTDC?

Yes. Since India's 6-digit PIN code system is standardized nationwide by the Department of Posts, the computed road kilometers and transit zones apply equally across India Post, Delhivery, Blue Dart, DTDC, Shadowfax, Ekart, and Xpressbees.

What formula is used to calculate distance between two PIN codes?

The tool computes the spherical geodesic distance using the Haversine formula based on official geographic coordinates of India Post offices, with an automated road curvature factor for highway transit.
