The bottom line is this. This is known as Caller ID spoofing. Telemarketers will call you disguised with this number and once you pick up - BAM! you're now a target for further telemarketers. Unfortunately, Republic Services does use this same phone number to legitimately give out service notices as well. File a complaint with the FCC on this - caller ID spoofing of legitimate businesses and government agencies is only going to get worse. Do a Google search on caller ID spoofing, lots of recent articles.
I basically have no choice but to block this number because they call about once a month. They called 5 times in the span of a minute this morning and Republic Services verified that there were no legitimate service notices out, plus my garbage and recycling was already picked up.
That is NOT TRUE do not believe the posters above and below. They are closed on Memorial Day here in the Midwest. Better check your area to make sure they are picking up otherwise you will have trash all over the place with the storms and wind.
