Understanding NSDL (Protean) vs UTIITSL PAN card portals
In India, new PAN card applications and PAN corrections are processed by two authorized service providers under the Income Tax Department: NSDL (now Protean eGov Technologies) and UTIITSL (UTI Infrastructure Technology and Services Limited). While both issue valid PAN cards, their online upload portals have specific file dimension requirements.
- Protean / NSDL Portal: Requires photo cropped to 3.5cm × 2.5cm or 213×213 pixels at 300 DPI, strictly under 50KB in JPG format.
- UTIITSL Portal: Accepts 2.5cm × 3.5cm photos at 300 DPI (213×213 pixels) and signature files under 50KB at 600 DPI for physical printing.
- e-KYC / Aadhaar OTP Mode: If applying via paperless e-Sign mode using Aadhaar OTP, your photo is fetched from UIDAI, but physical card submission or correction applications require manual upload.
