Five tools state a way to hide customers' phone numbers from agents, and each puts it on a higher tier: Periskope lists number masking on its home page, TimelinesAI from Pro, Gallabox on Advanced, respond.io on Advanced and Wassenger on Enterprise. If your reps should not be able to take the contact list with them, that is a requirement to check before you pick a plan. Read as of 27 October 2026.
What does each tool state?
| Tool | What its pages state | From which plan |
|---|---|---|
| Periskope | Number masking listed on the home page, with role-based permissions, audit logs and data exports | Not tied to a plan in the text we read |
| TimelinesAI | Hide phone numbers: not included on Starter, included on Pro and Enterprise | Pro, $49 per seat a month |
| Gallabox | Number masking among Advanced's additions | Advanced, ₹16,999 a month billed quarterly |
| respond.io | Mask phone number and email among Advanced's additions | Advanced, $279 a month billed yearly |
| Wassenger | Hidden phone numbers among Enterprise's additions, with fine-grained permissions | Enterprise, $99.90 a month |
| WATI, Interakt, AiSensy, DoubleTick, ChatDaddy | Masking not stated in the pages we read | Not stated |
| WavesFlo | Not a claim the site makes. Access is set by role and by number: an Agent sees only the chats assigned to them, and a number can be limited to named teams or people | Included |
Why does hiding a number matter?
- An agent who can see every customer's number can copy the list, and a leaver can take it.
- A masked number still lets the agent reply; the tool sends, the agent never sees the digits.
- It does not stop a customer's number appearing in a group they are in, or in a chat history on a phone that is linked.
- It is a control for a trust problem, so check it in the context of your roles and exports.
What should you ask before you commit?
- Is masking per role, per number or global?
- Can a user still export contacts, and does the export unmask?
- Does masking apply in groups and in the API?
- What does the audit log record about who viewed or exported a number?
- What happens to masked chats when an agent leaves?
Where does WavesFlo fit?
Bring the same question to a WavesFlo demo: roles and per-number access limit what an agent can reach, but masking a customer's number from an agent is not something this site claims. What an Agent does see is the chats assigned to them in the shared inbox, from the numbers they have been given.
Questions
Which WhatsApp tools can hide a customer's phone number?

No. The agent replies through the tool without seeing the digits.
Does WavesFlo mask phone numbers?
The site does not claim it. Access is set by role and number, and an Agent sees only the chats assigned to them.

Not alone. Check exports, audit logs and what a linked phone keeps.
