Testimonials

Customer Feedback After Using The Service

FBnumber saves me hours every day. I used to manually look up UIDs one by one — now I can scan hundreds from a single post's comments in minutes. Game changer for my ad targeting.

Nguyễn Văn Hùng

Facebook Ads Specialist

Before FBnumber, finding customer phone numbers on Facebook was a nightmare. Now I can export UIDs from my group members and run targeted Messenger campaigns. My conversion rate jumped to 60%.

Trần Thị Mai

E-commerce Store Owner

I use FBnumber daily to find UIDs from comments on real estate groups, then look up their phone numbers. Closed 15 deals last month from leads I found exclusively through FBnumber.

Lê Quang Minh

Real Estate Agent

Our agency manages 30+ client accounts. FBnumber is the first tool we install on every new team member's browser. Bulk UID scanning from likes, comments, and inbox — nothing else comes close.

Phạm Thanh Hương

Digital Marketing Agency Owner

My team of 12 uses FBnumber every day. We scan UIDs from competitor posts, look up phone numbers, and reach out. Our monthly leads doubled since we started using it. Highly recommended.

Hoàng Đức Thắng

Insurance Sales Team Lead

As a solo SDR, every lead counts. FBnumber lets me extract UIDs from any Facebook interaction — friend lists, group members, post likes. I've built a 5,000+ lead database almost entirely through this tool.
