How Manila's Public Records Ended Up Full of Duplicate Images — and What It's Costing the City

Manila's city government is now contending with a sprawling problem hiding inside its own filing systems: thousands of duplicate images embedded across public records databases, from barangay-level land titles digitised in the early 2000s to more recent building permit scans uploaded through the One-Stop Shop processing centre along A. Soriano Avenue. The redundancy has ballooned storage costs, slowed document retrieval, and in at least a handful of documented cases complicated title verification processes at the Registry of Deeds on J. Bocobo Street in Ermita.

The issue matters right now because the Marcos administration's broader push to unify local government digitisation under the Department of Information and Communications Technology's eGov Super App initiative — formally launched in phases starting 2023 — has thrown a harsh light on how inconsistent the underlying data actually is. If the national interoperability layer cannot reconcile duplicate files at the city level, the promised seamless government service delivery stalls before it starts.

How the Duplication Built Up Over Twenty Years

The roots go back to 2004, when the Metropolitan Manila Development Authority and individual local government units each ran separate scanning projects targeting the same sets of community maps and zoning documents. Barangay San Nicolas in Tondo and Barangay 659 in Paco were among the earliest pilot areas, and because both the MMDA's geographic information unit and the City Planning and Development Office were digitising simultaneously with no shared naming protocol, the same physical document routinely ended up with two or three different file entries across two separate servers.

That duplication compounded through subsequent programs. The Land Registration Authority's computerisation project, which accelerated after the 2009 Property Registration Decree amendments, pushed more scanned titles into circulation. The Department of the Interior and Local Government's DILG Seal of Good Local Governance compliance requirements after 2012 encouraged barangay halls to upload proof-of-service documents — often the same certificates already lodged centrally by the City Civil Registry on General Luna Street. Every new compliance layer added another upload requirement with no automated deduplication check built in.

By 2021, an internal audit commissioned by the Manila City Information Technology Department — not publicly released but referenced in a subsequent budget hearing transcript available through the Sangguniang Panlungsod — flagged an estimated 34 percent redundancy rate across the city's primary document management system. That figure has not been independently verified by this reporter, but city council deliberations that year did result in a line-item allocation for a records rationalisation study, suggesting the problem was acknowledged at the legislative level.

What the Cleanup Involves and Who Is Doing It

The current remediation effort sits with the Manila E-Government Office, which operates out of the Manila City Hall complex on Padre Burgos Avenue in Ermita. Their approach combines automated hash-matching software — which compares digital fingerprints of image files to find identical copies — with manual review by a team of archivists contracted through the National Archives of the Philippines. The manual layer is necessary because some duplicates are not pixel-perfect copies: a document scanned twice at different resolutions, or with a slightly different crop, reads as two distinct files to basic software but represents the same legal record.

The process is slow. Archivists must also determine which version of a duplicated image is the authoritative one — the higher-resolution scan, the one with a visible official stamp, or the one with an earlier upload timestamp — before the other can be safely flagged for deletion. Errors here carry real legal weight: a title image deleted in error could disrupt a property transaction at the Register of Deeds weeks later.

For ordinary Manileños, the practical consequence in the near term is that document requests through the City's online portal, accessible at manila.gov.ph, may return inconsistent results until the cleanup is complete. Anyone processing title verifications or building permit histories for properties in older districts like Binondo or Quiapo should request physical confirmation from the originating office alongside any digital copy. The E-Government Office has not announced a formal completion date for the rationalisation project, but budget documents for fiscal year 2026 allocate funds through December of this year.
