The prefixes 151x, 1530, 1540, 1550 (Initially 0300), 1559, 1560, 1570 and 1580 are for premium rate Services which are more expensive than other telephone calls. These numbers provide a range of services from weather forecasting to adult dating. Regtel an independent body monitors the premium rate services industry.Freephone services use the prefix 1800, while shared cost ( Lo-Call ) numbers use the prefix 1850. 1890 (local rate) numbers are issued to non-geographic services, with 0818 being charged at national rate, or slightly higher. One disadvantage of this arrangement is that Irish shared cost numbers are inaccessible from outside the Republic (unlike, for example, UK local and national rate numbers, which can be accessed by dialing 0044845 or 0044870), although numbers with the 0818 prefix can be dialled internationally, for example, as 00353818 from the UK. Consequently, many organisations that operate on both sides of the border advertise separate non-geographic numbers, for example, a 1800, 1850 or 0818 number for callers from the Republic, and an 0800, 0845 or 0870 number for callers from Northern Ireland. Dial-up Internet providers are entitled, but not required, to use numbers in the 189x range. 1891 numbers cost slightly below local call rate, and are often provided for subscription dialup packages. 1892 numbers are used for full local rate dialup, and 1893 for variable-rate dialup. A new area was introduced in 2005, using the 076 access code. This is allocated to VOIP providers, and is treated as either a national or local call by individual telecoms operators. The 13xxx code is used for accessing third party phone service providers and some internet services. These codes - route calls to local, mobile, national or long distance numbers. However, most customers use carrier preselect, where the local telephone switch automatically routes calls over their desired service provider(s
