Which countries have a social security agreement route, and which deadlines apply?

As of 14 October 2026, 33 of the 41 countries we research have at least one social security agreement route recorded in our data, each read on an official agreement list, and 23 of them have at least one route through a multilateral framework. Our deadline register holds 495 dated obligations across 41 of those countries. We now publish these figures each month as a citable data release, with CSV files in which every row carries its source URL and the date we read it.

What the release covers

The release brings three things together for each month. First, treaty routes: which of the countries we research have a social security agreement with one of the 98 other countries we have mapped, read on official agreement lists. Second, deadlines: the rows of our deadline register for every country we research, counted by type. Third, what changed: the month's entries from our monthly data changes, which list every change to our public data with its date.

Every number on the release page is computed from our data when the site is built. Nothing is typed by hand.

Treaty routes, by the list they were read on

Our data records 389 agreement routes between the countries we research and 53 mapped countries, read on 51 official lists, one sourced row per route. By the list they were read on:

• A national agreement list: 198 rows, 32 researched countries
• EU social security coordination: 159 rows, 20 researched countries
• Ibero-American Multilateral Social Security Agreement: 20 rows, 4 researched countries
• Social security coordination protocol of the EU and UK Trade and Cooperation Agreement: 8 rows, 1 researched countries
• GCC extension of insurance protection: 4 rows, 1 researched countries

We mark a route multilateral only where the list we read is the list of a multilateral framework. For Hong Kong, Indonesia, Malaysia, Mexico, Philippines, Singapore, South Africa and Vietnam, our data records no route with a mapped country yet. That is a gap in what we have read, not a finding that no agreement exists.

Deadlines, by type

The register rows for the countries we research fall into 14 types. The five largest are:

• Application window: 82 rows
• Other: 66 rows
• Forfeiture: 59 rows
• Proof of life: 49 rows
• Backdating limit: 40 rows

49 rows carry a fixed calendar date, and 10 of those dates fall after 14 October 2026. The next ones are:

• 31 December 2026, Slovenia, application window (row si-1)
• 1 January 2027, Belgium, transition date (row be-13)
• 31 March 2027, Singapore, arrears destroyed (row sg-8)
• 31 March 2027, Singapore, transition date (row sg-16)
• 5 April 2027, United Kingdom, transition date (row uk-6)

What changed in October 2026

We recorded 884 dated changes to our public data in October 2026, through 14 October 2026: 98 countries mapped, 36 country deadline pages added, 244 deadline register rows changed and 500 employer pages added. The monthly data changes list each one with a link to the row or page it describes.
