Colombia number screening
In Colombia the first digit does the work: 3 is mobile, 60 is a landline, and both run 10 digits.
Mobile number format
Colombian mobiles are 10 digits and always start with 3, typically in the 300–32x ranges. Since 2022 landlines are 10 digits too, formatted as 60 plus a one-digit regional code plus 7 digits — Bogotá is 601. The leading digit is what separates them.
Main carriers
- Claro
- Movistar
- Tigo
- WOM
Claro holds the largest share, with Movistar and Tigo behind it and WOM buying volume on price since launching in 2021. Prepaid dominates, top-ups are small and frequent, and lines cycle between suspended and active often enough that monthly rechecks matter more than in postpaid markets.
On the ground
Colombian wallets are built on the phone number itself: Nequi and Daviplata accounts are opened with it, so a number changing hands or lapsing breaks the payment path as well as the message. The country is also a major BPO call-centre base, which has left consumers noticeably wary of unknown inbound calls.
Screening guidance
Split on the leading digit first — keep 3, discard 60 — and you cut a large slice of wasted dialling before spending anything. Then check WhatsApp reachability and activity, and segment by age: Facebook for older contacts, Instagram and TikTok for younger ones. With prepaid churn this high, re-verify monthly.
Key platforms in Colombia
WhatsApp is the country's front door — most small merchants never build a website and run support straight through it. Facebook still holds older audiences, Instagram and TikTok take the younger end, and Telegram stays niche around communities and news.
FAQ
How many digits is a Colombian mobile number?
Ten, always starting with 3, typically in the 300 to 32x ranges, or twelve with the +57 country code. Colombian landlines are also ten digits now but start with 60, so the leading digit tells you immediately whether a record is mobile or fixed.
What is the difference between numbers starting 3 and 60 in Colombia?
3 marks a mobile line; 60 marks a landline under the 2022 renumbering, formatted as 60 plus a one-digit regional code plus seven digits, with Bogotá on 601. They are the same length now, so the first digit is the only clue. Dropping 60-prefixed records early saves a lot of wasted outreach.
Why do Colombian lists need re-verifying so often?
The market is prepaid-led, with small, frequent top-ups; when the balance runs out a line goes suspended and may come back weeks later. A one-off reachability result drifts noticeably within two or three months, so long-running campaigns should re-run verification monthly or per batch.
