How does 911 work for callers in Sebastian?
A 911 call or text from Sebastian goes to an Indian River County Public Safety Answering Point, where telecommunicators staff designated emergency lines twenty-four hours a day.
The county's 911 Administration page describes the system. 911 Administration is a division of the Indian River County Emergency Services Department, and the page names Sebastian along with Fellsmere, Indian River Shores and Vero Beach as areas where anyone needing emergency help should dial 911 on a landline or mobile phone. The Public Safety Answering Point telecommunicators operate designated emergency phone lines twenty-four (24) hours a day, so a call from a home in the Sebastian Highlands at 3 a.m. reaches a staffed line.
Inside the city limits, the Sebastian Police Department at 1201 Main Street lists 911 as its emergency phone on the City of Sebastian police page, and the same page gives a separate dispatch option, press 0, on the department's main line, 772-589-5233. That main line is for matters that are not emergencies.
| Method | What reaches the Indian River County call taker | Caveat |
|---|---|---|
| Traditional landline | Address and/or phone number displayed on screen | Shows the address the phone company has on file |
| Cell phone voice call | The call; the caller must know the location | Address may not be provided to 911 |
| VoIP or cable phone | Registered physical address, if kept current | Can fail in a power outage or fiber break |
| Text to 911 | Up to 140 characters, AT&T, Sprint, T-Mobile or Verizon | For when a call is not possible or speaking is unsafe |
| Calling from outside the county | Cannot reach county 911 centers | Use an agency non-emergency line, such as the Sebastian Police Department |
Florida law also sets a monthly 911 fee. Section 365.172, Florida Statutes sets the fee at 40 cents per month for each service identifier, effective January 1, 2015, and states that the fee shall apply uniformly and be imposed throughout the state, so a Sebastian service identifier carries the same 40-cent rate as one anywhere else in Florida.
Can Sebastian residents text 911?
Yes, since April 1, 2022, every Public Safety Answering Point in Indian River County, including those serving Sebastian, has accepted Text to 911 from AT&T, Sprint, T-Mobile and Verizon customers.
The county announced the change in a news release still posted on its 911 Administration page. Customers of the four major wireless carriers can send a text of up to 140 characters to 911 in an emergency. The county states that text provides the Deaf, Hard of Hearing, and Speech Impaired communities direct access to 911 services in Indian River County, Sebastian included.
Texting is the backup, not the default. The county says Text to 911 should only be used in an emergency situation, when placing a call is not possible or when speaking out loud would put the caller in danger. The county's address tips ask callers to always state where the emergency is at the start of a call, and a Sebastian text has 140 characters to carry that location.
The federal rules point the same way. The FCC text-to-911 guide states that voice calls to 911 provide more information to 911 call centers and that voice-based 911 service is still the most reliable and preferred method of contact. Where texting is not available, FCC rules require carriers to send an automatic bounce-back message telling the sender to contact emergency services by another means, such as a voice call or a telecommunications relay service. The bounce-back exists so that a sender, whether in Sebastian or traveling elsewhere, does not mistakenly believe a text reached a call center when it did not.
Does 911 know where a Sebastian caller is?
A traditional home landline displays the address and/or phone number on the Indian River County 911 call taker's screen; other Sebastian callers, including cell and internet phone users, must know their location.
The county's address tips page is direct about it. A Sebastian caller without traditional home phone service, the kind paid to a local provider that plugs straight into the wall, must know the location when calling 911, because the address and phone number may not be provided to 911. The page asks callers to state where the emergency is at the start of the call, since the call may need to be transferred to the correct call center.
On the road in or near Sebastian, the county asks callers to give the street being traveled, the most recent mile marker and the direction of travel.
For homes, the 911 address is the physical address with house number and street name; a route or box number cannot be used. The county asks that numbers be posted on the house or business, visible from the road, preferably in reflective material, and that driveways and lane entrances be marked rather than only the mailbox. Indian River County Planning Division is the official addressing authority, and missing street signs inside Sebastian are reported to City Hall, according to the same page.
Multi-unit buildings add one more step. The county's phone tips page tells callers in an apartment, condominium, motel or hotel to give the operator the unit number and the floor, which applies to any multi-unit building in Sebastian.
What should Sebastian VoIP and cable phone users know about 911?
Sebastian homes with internet or cable phone service can lose 911 in a power outage or fiber break, and the service sends only the address the customer registered with the provider.
The Indian River County phone tips page states that a telephone using the internet (VoIP) or cable services for connectivity risks losing service if there is a power outage or fiber break. After a move, the customer must give the VoIP provider the accurate physical address where the phone is located, and the county calls keeping that account information current the customer's responsibility. For Sebastian households facing storm outages, the FCC suggests a backup power supply, a traditional phone line or a wireless phone as a backup.
The FCC VoIP and 911 guide explains why. VoIP 911 calls may not connect to the 911 call center serving the caller's current location, or may connect without automatically transmitting the caller's phone number or location. The FCC requires interconnected VoIP providers to obtain a customer's physical location prior to service activation and to offer one or more easy ways to update it. A seasonal resident who carries a VoIP device between a northern home and a winter address in Sebastian needs the Sebastian address registered while in Florida.
The county's resident information page repeats the point for visitors and part-time residents in Indian River County: always know the location or address, and have the VoIP service provider update the address and location.
What if a call comes from outside Indian River County or 911 is dialed by mistake?
A person outside Indian River County cannot dial into the county's 911 centers for someone in Sebastian, and a Sebastian caller who dials 911 by mistake should stay on the line.
On the first point, the county's 911 Administration page states that it is not possible to reach its 911 dispatch centers from outside Indian River County. A relative in another state worried about a parent in Sebastian calls a non-emergency number instead, and the county page lists the Sebastian Police Department at (772) 589-5233 and the Indian River County Sheriff's Office at (772) 569-6700 as agencies that can alert emergency services and get responders on the way.
On the second, the phone tips page explains the county's policy. If a Sebastian caller dials 911 by mistake and hangs up, the call taker tries to call the number back and reach an adult; if no contact is made, law enforcement will be dispatched to verify there is not a problem. Staying on the line and confirming that there is no emergency, along with the address, avoids that trip. The page adds that old deactivated cellular phones can still call 911 as long as the battery is charged, a reason to remove the battery before handing one to a child.
The county's resident information page lists a few steps that help responders reach a Sebastian home: a list of medications where EMTs can find it, a spare key with a trusted neighbor, and, for a caller who cannot talk, calling 911 anyway and leaving the phone nearby.
