Overview
CLI routes to Italy
A CLI route to Italy is a wholesale path that keeps the caller ID you send intact all the way to the handset. CLIRoutes only places CLI-tier traffic on paths that passed CLI test calls on Italy’s main networks, and removes paths that stop passing.
Italian CLI routes carry your number on paths that comply with AGCOM’s anti-spoofing rules. We test fixed and mobile CLIs separately, because they are subject to different blocking timelines.
Italy has an active outsourced customer-care sector and strict enforcement against aggressive telemarketing. Calls presenting unregistered or unidentifiable numbers are a recurring enforcement target.

Dialing & setup
Dialing Italy correctly
- Keep the leading 0 on fixed numbers: 06 1234 5678 becomes +39 06 1234 5678. Italy is one of the few countries where the 0 stays.
- Mobiles start with 3 and have no leading 0: +39 312 345 6789.
- Check the RPO before marketing calls; since 2022 it covers mobile numbers and cancels prior consents when someone registers.
- August (Ferragosto) sees a sharp drop in B2B answer rates.
Caller ID best practice
Present an Italian number assigned to you that is recognisable and callable, and keep CLIs consistent across campaigns.

Italy CLI routes: FAQ
Can’t find what you need? Our routing team answers within the hour, around the clock.
Do I need to scrub against the Registro delle Opposizioni?
Yes, for marketing calls. The register covers landlines and mobiles, and scrubbing is a condition of running marketing campaigns on our Italian routes.
What answer rates can I expect in Italy?
They depend on the CLI and on the campaign. Italian numbers you hold perform best. Your portal shows live ASR and ACD for Italian destinations so you can compare.
Why must I keep the 0 in Italian numbers?
Italy integrated the 0 into fixed numbers in 1998, so it is part of the number, not a trunk prefix. Dropping it produces an invalid number.
What changed with AGCOM’s anti-spoofing rules?
Operators now block international-origin calls presenting Italian numbers unless they are legitimate, starting with fixed numbers and extending to mobiles in November 2025. Italian CLIs must be used on properly originated traffic.
Does the RPO cover mobile numbers?
Yes, since July 2022. Registering also revokes consents given earlier, so check the register before every campaign even if you hold consent.
Which caller ID can I present on Italy calls?
Only numbers you own or are authorised to use. Present an Italian number assigned to you that is recognisable and callable, and keep CLIs consistent across campaigns.
