How to Name Files for UKVI Visa Applications

TL;DR

UKVI doesn't enforce filename rules but caseworkers process applications faster when files are named consistently: numbered prefix, descriptive type, your surname (e.g. 01_Passport_BioPage_Garcia.pdf). Our Bundler renames files automatically using Home Office conventions when you build a merged bundle.

How to name files for UKVI

1. Use the format NN_DocumentType_YourLastName.pdf, number first for sort order, descriptive name in the middle, surname last
2. Number sequentially (01, 02, 03…) so files appear in canonical order even when uploaded separately
3. Use underscores not spaces, some upload systems mangle filenames with spaces
4. PascalCase the document type, Bank_Statement not bank statement
5. For periodic documents include the period, 04_Bank_Statement_2025-10_Garcia.pdf for October 2025
6. For multi-page categories, use sub-numbering, 03a_Bank_Statement_Sept.pdf, 03b_Bank_Statement_Aug.pdf
7. Keep filenames under 60 characters, some systems truncate longer names

Recommended document types

Why naming matters

UKVI caseworkers see hundreds of files weekly. Consistent naming:

• Saves caseworker time, they find the document UKVI's checklist asks for without opening every file
• Reduces resubmission requests, if a file is named IMG_4837.JPG, the caseworker may not realise it's your sponsor letter and request "the missing employer letter"
• Survives re-uploads, if you have to re-upload a single file, a clear name makes it obvious which one
• Helps your future self, if there's an issue 6 months later, you can find evidence quickly in your local backup

What to avoid

• Phone defaults like IMG_4837.JPG, Document_2026.pdf, Scan_001.pdf
• Personal references like Mom_Bank_Statement.pdf, caseworkers don't know who "Mom" is
• Dates in ambiguous formats like 04-05-2026 (could be 4 May or 5 April)
• Special characters like &, #, %, +, many upload systems break on these
• Camera-app PDFs named like IMG_20260501_143245.pdf
• WhatsApp downloads named like IMG-20260501-WA0042.jpg

When the Bundler renames automatically

If you use our free Bundler to merge documents into a single PDF, the filenames inside the bundle's index page are normalised automatically using Home Office conventions:

• IMG_4837.JPG → 01_Passport_BioPage.pdf (when categorised as passport, position 1)
• Statement.pdf → 04_Bank_Statement.pdf (when categorised as financial, position 4)

The original filenames are preserved in the file list (so you don't lose track), but the bundled PDF's index page shows the normalised names, that's what caseworkers see.

What about the bundled file itself

For the merged bundle, the Bundler suggests:

{route}_{your-name}_{date}.pdf, e.g. skilled-worker_maria-garcia_2026-05-01.pdf

This is what UKVCAS / VFS Global sees as the upload filename. It tells caseworkers immediately what application this relates to.
