WIA Pin Code Proposal — Haiti

1 Summary

This document describes how WIA Pin Code, a free 12-digit coordinate code, could be used alongside Haiti's existing addresses, postcodes and address systems. It does not propose replacing any national system.

                    Key facts:
                    12-digit code (XXX-XXX-XXX-XXX); each code identifies a cell of about 20 m × 40 m at the equator
Calculated from coordinates alone, so conversion works without an internet connection
Free for governments and individuals
Published formula (YUJIN Transform v2), so results can be checked independently

                

2 Current Addressing Situation (as of 14 October 2026)

Classification: E — National postcode in place; no national digital addressing system found

Haiti has a four-digit "HT" postal code administered by the national post; no national digital addressing system was found.

Population: 11.9M (World Bank, 2025)
Rural population: 44.4% (World Bank, 2025)

Global context: the Universal Postal Union notes that “the absence of a complete, correct and unique national address infrastructure constitutes a major socio-economic challenge for a number of developing countries” (Addressing the world – An address for everyone, 2012, p. 7).

3 WIA Pin Code

WIA Pin Code uses the YUJIN Transform v2 formula (Yeon Sam-heum, Ph.D.) to convert GPS coordinates into a 12-digit code.

                    Example point in Haiti:

                    GPS: 18.97°, -72.29° → WIA Pin Code: ---

Technical specifications:

Format: XXX-XXX-XXX-XXX (12 digits)
Cell size: about 20 m north–south everywhere; about 40 m east–west at the equator, narrower towards the poles
Backward compatible: the first nine digits are the v1 code (2025); a v1 code alone covers a strip about 20 m × 40 km and is not a house-level address
Coverage: the whole Earth, including all of Haiti
Offline: code calculation needs no internet connection; maps and search do
Personal data: the code is computed from coordinates only and contains no personal data
Specification: https://wiapincode.smilestory.ai/docs/yujin-transform.html

4 Possible Next Steps (to be agreed with national authorities)

Step 1 — Conversation and interoperability check

Understand the national address, postcode or digital address programme
Test how WIA Pin Codes map to existing records; the national system remains the reference

Step 2 — Small local pilot (scope agreed locally)

Area, partners and duration agreed with the responsible authorities
Free use of the code-calculation API, the WIA GIL map and the MCP server

Step 3 — Joint review

Review the results together and publish only what the data show
The national authority decides whether and how to continue

6 What This Proposal Does Not Claim

It does not replace national addresses, postcodes or digital address systems.
It does not promise economic, emergency-response or delivery figures; any effect would have to be measured in a pilot.
A WIA Pin Code identifies a cell of about 20 m × 40 m, not a specific door or household.
