Most spam campaigns dial from blocks of consecutive numbers that share the same opening digits. Instead of blocking them one by one, Prefixly lets you block an entire range with one short prefix. HOW IT WORKS • Choose country prefix e.g. +91. Enter the digits after +91. A full 10-digit number blocks just that caller; a shorter prefix blocks every number that starts with it. • Example: the prefix "7713105" blocks +91 7713105000 through +91 7713105999 — 1,000 numbers in a single tap. • CallShield registers these with iOS so matching calls are silenced automatically, and an optional label (like "Spam") shows on the incoming call screen. FEATURES • Block by prefix — one short prefix covers thousands of numbers • Custom labels shown on the incoming call screen • Toggle prefixes on or off without deleting them • Live capacity and protection-status indicators • 100% on-device — your block list never leaves your iPhone PRIVACY Prefixly collects no personal data and has no accounts, ads, or trackers. Your block list is stored only on your device. SETUP After installing, enable Prefixly under Settings → Phone → Call Blocking & Identification. The app walks you through it. Prefixly uses Apple's CallKit Call Directory and works on iPhone with iOS 17 or later. It cannot block numbers you haven't added, and it does not access your call history or contacts. ## Prefixly Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/b0/bd/e3/b0bde32a-258f-86a0-cd24-73ab744e84cc/01.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/57/cd/12/57cd12ca-86e5-128f-2105-c9c58d5fc220/02.png/1284x2778.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/57/d0/36/57d0360f-e369-94fc-6040-07040c53ac09/03.png/1284x2778.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/1a/4e/da/1a4edaf7-3617-d80c-69e1-d2d3c7c8a83d/04.png/1284x2778.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0a/a7/13/0aa71380-f79f-a4cf-31c9-77d74758def4/05.png/1284x2778.png) ## Prefixly Rating Breakdown in India - 5 stars: 2 (67%) - 4 stars: 0 (0%) - 3 stars: 1 (33%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Prefixly Available In - [India](https://apptail.io/app/prefixly-block-spam-calls-eoLA/india) - [Canada](https://apptail.io/app/prefixly-block-spam-calls-eoLA/canada) - [United States](https://apptail.io/app/prefixly-block-spam-calls-eoLA/united-states) - [Brazil](https://apptail.io/app/prefixly-block-spam-calls-eoLA/brazil) - [China](https://apptail.io/app/prefixly-block-spam-calls-eoLA/china) - [Ecuador](https://apptail.io/app/prefixly-block-spam-calls-eoLA/ecuador) - [United Kingdom](https://apptail.io/app/prefixly-block-spam-calls-eoLA/united-kingdom) - [Honduras](https://apptail.io/app/prefixly-block-spam-calls-eoLA/honduras) - [Israel](https://apptail.io/app/prefixly-block-spam-calls-eoLA/israel) - [Japan](https://apptail.io/app/prefixly-block-spam-calls-eoLA/japan) - [Kenya](https://apptail.io/app/prefixly-block-spam-calls-eoLA/kenya) - [Lebanon](https://apptail.io/app/prefixly-block-spam-calls-eoLA/lebanon) - [Sri Lanka](https://apptail.io/app/prefixly-block-spam-calls-eoLA/sri-lanka) - [Oman](https://apptail.io/app/prefixly-block-spam-calls-eoLA/oman) - [Pakistan](https://apptail.io/app/prefixly-block-spam-calls-eoLA/pakistan) - [Russia](https://apptail.io/app/prefixly-block-spam-calls-eoLA/russia) - [Singapore](https://apptail.io/app/prefixly-block-spam-calls-eoLA/singapore) - [Uzbekistan](https://apptail.io/app/prefixly-block-spam-calls-eoLA/uzbekistan) - [Vietnam](https://apptail.io/app/prefixly-block-spam-calls-eoLA/vietnam) - [Armenia](https://apptail.io/app/prefixly-block-spam-calls-eoLA/armenia) - [South Africa](https://apptail.io/app/prefixly-block-spam-calls-eoLA/south-africa) - [Australia](https://apptail.io/app/prefixly-block-spam-calls-eoLA/australia) - [Bahrain](https://apptail.io/app/prefixly-block-spam-calls-eoLA/bahrain) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
