The Department of Home Affairs will this week intensify its campaign to eradicate more than 29 000 duplicate identity documents.
The department will publish the names of those affected by duplicate IDs in more national newspapers this week, after names were published in some newspapers last week.
Home Affairs Minister Nkosazana Dlamini Zuma launched a campaign to deal with the issue of duplicate IDs on 11 May.
The minister reiterated her appeal to those whose names appeared on the department's website and in media to approach their nearest Home Affairs offices to have their case resolved.
In an effort to speedily and efficiently resolve cases of duplicate IDs, all Home Affairs offices have established dedicated counters and personnel to assist those affected.
The department has also activated its SMS service to enable South Africans to check their ID status.
Citizens can send a SMS with the letter "D" followed by their ID number to 32551. They will then receive a response informing them if they are one of those affected.
"We will also be building strategic partnerships with relevant organisations to mobilise those affected by duplicate IDs behind this campaign so that they too can, together with their fellow South Africans, enjoy the benefits of a better life for all," the department said.
