Agencies shouldn't run client logins off someone's personal phone
Use dedicated, non-VoIP, real-SIM US numbers for your client accounts so verification codes land in a shared inbox your whole agency team can access. JoltSMS gives you notifications and Team Access so you can manage logins without juggling devices.
- Keep client account verification away from personal phones
- Use real-SIM, non-VoIP US numbers that work where VoIP fails
- See all verification SMS in one shared inbox
- Route codes to Slack/Discord/Email/Webhooks for your team

A shared inbox for all your clients' verification codes.
Client account access shouldn't depend on one account manager's phone
Agencies juggle logins for ad platforms, social accounts, marketplaces, and tools. When verification codes go to one person's phone—or to a cheap VoIP app—you end up locked out at the worst times.
| Problem | What it looks like for agencies |
|---|---|
| Account manager lock-in | One AM's personal phone tied to Facebook Ads, Google Ads, TikTok, etc. |
| Turnover risk | When that person leaves, nobody can get codes to log in or recover accounts. |
| VoIP failures | "Second number" apps work for calls but get rejected or fail for verification. |
| Scramble for codes | Team chats full of "Screenshot the code for me now!" messages. |
| No central visibility | No one place to see which numbers are used for which clients/platforms. |
A shared, client-safe way to handle verification codes
JoltSMS gives you dedicated non-VoIP numbers that belong to your agency (or your client), plus a shared inbox and roles so you can manage verification codes as a team.
- Dedicated non-VoIP, real-SIM US numbers you can label by client or platform
- Long-term rentals so codes keep working through re-verifications and policy changes
- Shared inbox so AMs, strategists, and ops see the same codes
- Notifications to Slack/Discord/Email/Webhooks for fast access
- Team Access roles so you can give each person the right level of control

Label numbers by client or platform—'Client A Ads', 'Client B Social', 'Internal Accounts'.
Common ways agencies use JoltSMS
Paid media & ad accounts
Google Ads, Meta Ads, TikTok, LinkedIn Ads, etc. Team needs access to verification codes when logging in or changing settings.
Social & brand accounts
Instagram, Facebook Pages, LinkedIn, Twitter/X, etc. Codes should go to a shared number, not one social media manager's phone.
Marketplaces & listings
Amazon Seller, eBay, marketplaces where you manage listings for clients. Phone verification is required to maintain or recover access.
Internal agency tools
CRMs, analytics, project tools that still use SMS verification. Keep those tied to a central agency number.
How an agency typically rolls out JoltSMS
Decide on your structure
Start with one number per client or per platform cluster (e.g., "All Ads Accounts", "All Social Accounts"), depending on your size.
Rent and label numbers
Rent dedicated non-VoIP US numbers in JoltSMS. Label them clearly: "Client A – Ads", "Client B – Social", "Agency Internal", etc.
Update account phone numbers
For client accounts you manage (with permission), set the JoltSMS number as the verification number for those logins.
Configure notifications for your team
Route codes to Slack/Discord channels and/or Email lists your AMs and ops use—e.g., #client-a, #paid-media-team.
Use the inbox as the central source of truth
When codes arrive, whoever is working can grab them from the inbox or Slack. No more waiting for "the person with the phone".
Add more numbers as clients and complexity grow
As you add more clients or platforms, provision additional labeled numbers accordingly.

Let the right people see codes, without over-sharing control
Agencies often mix account managers, media buyers, strategists, and leadership across clients. JoltSMS Team Access lets you share visibility without giving everyone billing or cancellation rights.
- Up to 10 team members per number
- Owner – retains billing and cancellation control (agency owner/ops lead)
- Manager – can see messages and configure notification endpoints
- Viewer – read-only access for leadership or limited roles
- Invites expire after 7 days to avoid stale access links

Get verification codes in your agency's real workflow
Most modern agencies live in Slack, Discord, and Email. JoltSMS routes verification codes there so your team doesn't have to sit in yet another tab.
- Slack – send codes to #client-a, #paid-social, #logins channels
- Discord – perfect for dev-heavy or remote-first teams
- Email – great for account owners, directors, or client service roles
- Webhooks – push data into your own internal tools or logging

Keep ownership clear when clients join, grow, or leave
Agencies need clean handoffs—both when onboarding new clients and when engagements end. JoltSMS makes it easier to control who owns and pays for key phone numbers.
When onboarding a client
- •Decide whether the number is owned by your agency or the client.
- •If agency-owned, use your JoltSMS account and share access internally.
- •If client-owned, consider setting them up with their own JoltSMS account and collaborating around that.
When offboarding a client
- •If the client will continue using those accounts, decide whether to:
- –Transfer ownership by moving to a client-managed JoltSMS setup (if supported by your ops), or
- –Update account phone numbers back to the client's own numbers.
- •Remove your staff from Team Access roles for that client's numbers.
FAQ for agencies & service providers
Smaller agencies sometimes start with one number for several related accounts, but for privacy and clarity we generally recommend separate, clearly labeled numbers per client or major client cluster.
Give your agency a clean way to handle client verification codes
Stop chasing screenshots and personal phones. Use dedicated non-VoIP numbers, a shared inbox, notifications, and Team Access to manage client logins like a proper system.
