How Long Should a Voicemail Greeting Be?
The short answer: 15 to 25 seconds. Long enough to identify your business, set expectations and give a clear next step. Short enough that callers don't hang up before the beep.

The time budget for a 20-second greeting
- 0–3 s — identification. "Thank you for calling [Company Name]" or "You've reached…"
- 3–10 s — context. Why the caller is hearing voicemail and what they should do next.
- 10–18 s — callback expectation. When to expect a return call. Optional alternative channels.
- 18–25 s — sign-off. A brief brand line or polite close. Optional.
Anything outside this budget falls into one of two failure modes: under 10 seconds (caller doesn't know what to do), or over 30 seconds (caller hangs up before the beep).
Length by greeting type
- Personal extension / mobile
10–15 seconds. Name, "leave a message", callback timeframe. - Main business line
15–25 seconds. Company name, hours or reason, what to do, when you'll call back. - After-hours greeting
15–25 seconds. Add "we're closed", reopen time and an alternative channel.
- Holiday greeting
20–30 seconds. Closure dates and reopen date are essential — even at the cost of length. - Auto attendant opening
5–10 seconds. The menu options follow; keep the opening short so callers reach the options fast. - IVR menu
15–25 seconds for up to 5 options. Beyond that, recognition rates collapse.
Why short wins
Listening data from contact centers consistently shows three things:
- Callers form an opinion about whether to keep listening within the first 3 seconds. If you haven't identified your business by then, they're already drifting.
- Hang-up rates rise sharply after the 20-second mark. Most callers who reach 20 seconds without hearing the beep assume the greeting is broken.
- Repeat callers (existing customers, returning leads) want the beep fast. Force them through a 40-second greeting and they'll stop calling.

Frequently asked questions
Almost always yes. Listening rates drop sharply after 20 seconds. Use 30 seconds only when you have a complex routing case (after-hours + emergency line + holiday closure all in one).
Yes — if you can fit company name, what to do next and a callback expectation. Personal extensions and mobile lines often do this well.
Most carriers cap voicemail greetings between 30 and 60 seconds. RingCentral, Microsoft Teams Phone and Zoom Phone all accept up to 60 seconds for personal voicemail. Auto attendant greetings can go longer (typically 3–5 minutes) but should not.
