Use type="tel" not type="text"
Mobile keyboards open the numeric keypad for tel inputs. Desktop accepts the same characters as text but signals intent.

Copy and ship
Your Phone Number Input Form, ready to paste.
HTML by default — the same field set also renders as React, Next.js, PHP, and cURL in your dashboard. Every variant posts to the same /api/submit endpoint. Replace YOUR_ACCESS_KEY with the key from your dashboard; that's the only edit.

How to add a Phone Number Input Form to your site.
To add a Phone Number Input Form to your site you need three things: a free splitforms access key, the HTML snippet above, and your key pasted into it. No backend, database, or CAPTCHA library — the form posts to one URL and every submission lands in your inbox and dashboard.
Add a pattern attribute for validation
`pattern="[0-9() +-]+"` allows the common phone characters. Or use a strict US format: `pattern="\(?\d{3}\)?[ -]?\d{3}[ -]?\d{4}"`.
(Optional) Add the JS mask
On input, strip non-digits and reformat to `(XXX) XXX-XXXX`. The mask runs on every keystroke, giving live formatting feedback.
What's included
What's in this Phone Number Input Form template?
Phone fields suffer from format chaos — users type +1 555 123 4567, (555) 123 4567, 555.123.4567, 5551234567. Three options: accept anything and normalize server-side (best for international), use a pattern attribute for client-side validation (good for US-only), or apply a JavaScript mask that formats as the user types (highest conversion, more code). splitforms accepts any format and your form's UX is whichever approach fits your audience. Mobile-friendly numeric keypad, live mask, format-tolerant.

Testimonials
Loved by developers shipping at every scale.
40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Questions
Phone Number Input Form questions.
View all FAQsWhy use type="tel" if it doesn't do anything special on desktop?
Two reasons. (1) Mobile keyboards: tel triggers the numeric keypad, dramatically reducing typos. (2) Accessibility: screen readers announce the field type, helping users with assistive tech understand what's expected. The 'no desktop benefit' is a feature, not a bug — the behavior matches user intent.
Should I validate international or US-only?
Depends on your audience. International contact forms should accept any format (use a permissive pattern + server-side normalization). US-only forms can use a strict pattern that matches `(555) 123-4567`. Either way, splitforms accepts whatever format the user submits — the validation is for UX, not data integrity.
Does the JS mask work with paste?
Yes — listen for both `input` and `paste` events, and reformat on every change. The pattern only validates on submit, so the mask gives live feedback as the user types or pastes.
What about the libphonenumber-js library?
Google's libphonenumber (and its JS port) is the gold standard for international phone validation. It's ~80KB minified, so only use it if international validation accuracy is critical. For most contact forms, a pattern + a tel input is enough.
