It is a subkey of ref=* and its values are numbers used as identifiers for population units, both by the Instituto Nacional de Estadística (Spain), P772 and the Instituto Nacional de Estatística (Portugal), P6324, even though their composition differs.

Spain

Subdivision	Digits	Reference formula	Notes
Province	PP	--	There is no ref:ine=* for provinces admin_level=6
Municipality	MMM	ine:municipio=* (PP + MMM) + "000000"	Only for relations boundary=administrative and admin_level=8
Collective entity	CC	ine:municipio=* (PP + MMM) + CC + "0000"	Only for relations boundary=administrative and admin_level=9
Singular entity	SS	ine:municipio=* (PP + MMM) + CC + SS + "00"	If the entity is a node, do not use this code, the nucleus code is preferable
Nucleus/scattering	NN	ine:municipio=* (PP + MMM) + CC + SS + NN	Only for nodes: in nucleus elements NN can be 01, 02, 03, 04, etc... and in scattered elements NN is equal to 99

Validation queries

Nodes

The spanish localities (i.e. place=*) ref:ine=* code lies in the value of ine:municipio=* plus 6 digits, therefore we can check it out using maths.

The next overpass query checks if the nodes contain the proper value, that is ine:municipio * 1e6 < ref:ine < ine:municipio * 1e6 + 1e6. If the following query returns nothing, it means everything is OK.

Note: The next query takes several minutes to run.

try it yourself in overpass-turbo

[out:xml][timeout:900];
area["ISO3166-1"="ES"]->.searchArea;
relation["admin_level"="8"]["ine:municipio"]["boundary"="administrative"](area.searchArea);
map_to_area;
foreach->.mun(
  (
    // como no existe un operador de substring, convertimos ambas etiquetas a números
    // (debido a un error de parseo de variables que empiezan en cero, se añade y luego se resta, un número superior a los códigos)
    // como el ref:ine tiene 6 cifras añadidas a su ine:municipio, multiplicamos por 1 millón
    // de tal modo que los ref:ine deberá pertenecer al rango: 
    // ine:municipio * 1e6 < ref:ine < ine:municipio * 1e6 + 1e6
    //
    // ejemplo:
    // ine:municipio=47140
    // ref:ine=47140000100
    //
    // 47140 * 1e6 < 47140000100 < 47140 * 1e6 + 1e6
    node(area.mun)["ref:ine"](if: (number(1e12 + t["ref:ine"]) - 1e12) < ((number(1e12 + mun.u(t["ine:municipio"])) - 1e12) * 1e6));
    node(area.mun)["ref:ine"](if: (number(1e12 + t["ref:ine"]) - 1e12) > ((number(1e12 + mun.u(t["ine:municipio"])) - 1e12) * 1e6 + 1e6));
  );
  out;
);

Likewise, we can further refine the entities validation, instead of consulting by municipality we do so by a lower unit, such as, the civil parishes for Galicia and Asturias, or the deputations/districts for Region of Murcia. A reference will be correct whenever: ref:ine parish < ref:ine locality < ref:ine parish + 1e4. If the following query returns nothing, it means everything is OK.

Note: This query will make sense whenever the municipalities contain boundary=administrative and admin_level=9 relations.

[out:xml][timeout:900];
area["ISO3166-2"="ES-GA"]->.searchArea;
relation["admin_level"="9"]["boundary"="administrative"](area.searchArea);
map_to_area;
foreach->.mun(
  (
    node(area.mun)["ref:ine"](if: (number(1e12 + t["ref:ine"]) - 1e12) < (number(1e12 + mun.u(t["ref:ine"])) - 1e12));
    node(area.mun)["ref:ine"](if: (number(1e12 + t["ref:ine"]) - 1e12) > (number(1e12 + mun.u(t["ref:ine"])) - 1e12 + 1e4));
  );
  out;
);

Relations

The spanish municipalities (i.e. admin_level=8) ref:ine=* code lies in the value of ine:municipio=* plus 6 zeros, therefore we can check it out using maths.

The next overpass query checks if the relations contain the proper value, that is ine:municipio * 1e6 = ref:ine. If the following query returns nothing, it means everything is OK.

try it yourself in overpass-turbo

[out:xml][timeout:900];
area["ISO3166-1"="ES"]->.searchArea;
relation["admin_level"="8"]["ine:municipio"]["boundary"="administrative"](area.searchArea)->.all;
relation.all["ref:ine"]->.ok;
// relaciones cuyo código ref:ine difiere del ine:municipio
// (debido a un error de parseo de variables que empiezan en cero, se añade y luego se resta, un número superior a los códigos)
//
// ejemplo:
// ine:municipio=47140
// ref:ine=47140000000
//
// 47140 * 1e6 = 47140000000
relation.ok(if: ((number(1e12 + _.set(t["ine:municipio"])) - 1e12) * 1e6) != (number(1e12 + _.set(t["ref:ine"])) - 1e12))->.wrong;
// relaciones sin código ref:ine
(.all; - .ok;)->.missing;
(.missing;.wrong;);
out geom;
