Extract Vietnam Phone Numbers from Text
Paste any text containing Vietnam phone numbers and NumSwift identifies them instantly. Vietnamese mobile numbers are 10 digits locally starting with 0. The trunk prefix 0 is dropped for international dialing, leaving 9 digits after the country code. After a 2018 migration, all mobile numbers use the new prefix format. NumSwift recognises both local formats like 091 234 5678 and international formats like +84 91 234 5678, validating each number against Vietnam's numbering rules.

Frequently Asked Questions
▶How many digits does a Vietnam phone number have?
Vietnamese mobile numbers are 10 digits locally starting with 0. The trunk prefix 0 is dropped for international dialing, leaving 9 digits after the country code. After a 2018 migration, all mobile numbers use the new prefix format. NumSwift accounts for all valid lengths when extracting numbers, so both mobile and landline formats are detected correctly.
▶Can NumSwift extract Vietnam numbers written in local format?
Yes. NumSwift recognises Vietnam numbers in local format (091 234 5678), international format (+84 91 234 5678), and various other common notations including with dots, dashes, or spaces as separators. The extraction engine is powered by Google's libphonenumber library, which supports all standard formats.
▶Does it work if the text mixes Vietnam numbers with numbers from other countries?
NumSwift handles mixed-country text seamlessly. It identifies each number's country of origin based on the prefix and formatting patterns, so Vietnam (+84) numbers are correctly distinguished from numbers belonging to other countries in the same text block.
▶Can I tell which Vietnam carrier a number belongs to from the extracted results?
The leading digits of a Vietnam mobile number often indicate the carrier — for example, Viettel and Mobifone each have recognisable prefix ranges. NumSwift extracts and displays the full number, allowing you to identify the likely carrier from the prefix based on Vietnam's numbering allocations.
